Figure 1 shows the CRM operating at the boundary between Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM).In CRM, the power switch turns on immediately when the inductor current decreases to zero. The CRM is the preferred control method for medium power (<300W) applications due to the features of zero current switching and lower peak current than that in DCM.Figure 1. Inductor Current of DCM, CRM and CCM Constant On-Time Voltage Mode ControlFigure 2 shows a typical flyback converter. When the MOSFET turns on with a fixed on-time (t ON ), the inductor current can be calculated by the following equation (1).TX1OUTV OUTFigure 2. Typical flyback ConverterIN L_PK ON PFCVI = t (1)L⨯If the input voltage is a sinusoidal waveform and rectified by a bridge rectifier, the inductor current can be expressed with equation (2). When the converter operates in CRM with constant on-time voltage modecontrol, the envelope of inductor peak current will follow the input voltage waveform with in-phase. The average inductor current will be half of the peak current shown as Figure 3. Therefore, the near unity power factor is easy to be achieved by this control scheme.||||IN_pk ONL_pk PFCV sin θt I sin θ=(2)L ⨯⨯⨯I L_PK I Q1I in_avg I DOUTPeak Inductor Current MOSFET Current Average Input Current Output Diode CurrentV IN Input Voltage V Q1_GATE MOSFET Gate VoltageFigure 3. Inductor Current of CRM with ConstantOn-Time Voltage Mode Control Under-Voltage LockoutThe controller will be enabled when VDD exceeds V ON_TH (16V typ.) and disabled when VDD decreases lower than V OFF_TH (9V typ.).The maximum VDD voltage is set at 27V typically forover-voltage protection shown as Figure 4. An internal 29V zener diode is also used to avoid over voltage stress for the internal circuits.When the VDD is available, the precise reference is generated for internal circuitries such as Error Amplifier, Current Sense, OVP, UVP. The internal reference equips with excellent temperature coefficient performance so that the RT7313 can be operated in varied environments.RT7313Copyright © 2016 Richtek Technology Corporation. All rights reserved. is a registered trademark of Richtek Technology Corporation.DS7313-01 July 20164Figure 4. VDD and UVLOFeedback Voltage DetectionFigure 5 shows the feedback voltage detection circuit. The INV pin is the inverting input of the Error Amplifier with 1.5V reference voltage. Over-voltage protection is provided with threshold voltage 1.65V. If the INV voltage is over 1.65V, the gate driver will be disabled to prevent output over voltage condition or feedback open condition. Although the INV is an input pin with high impedance, it is suggested that the bias current of the potential divider should be over 30µA for noise immunity.Figure 5. Feedback Voltage DetectionTransconductance Error AmplifierThe RT7313 implements transconductance error amplifier with non-linear GM design to regulate the Flyback output voltage and provide fast dynamic response. The transconductance value is 100µA/V in normal operation. When the INV voltage increases over 1.65V or decreases under 1.35V, the output of error amplifier will source or sink 1.5mA(typ.) maximum current at COMP pin respectively shown as Figure 6. Thus, the non-linear GM design can provide fast response for the dynamic load of PFC converters even though the bandwidth of control loop is lower than linefrequency.Figure 6. Non-linear GMFeed-Forward CompensationThe FF pin is an input pin with high impedance to detect the line input voltage shown as Figure 7. A proper voltage divider should be applied to sense the line voltage after bridge diode rectifier. Since the FF voltage is proportional to the line input voltage, it provides a feed-forward signal to compensate the loop bandwidth for high line and low line input conditions.Figure 7.

Ramp GeneratorThe RT7313 provides constant on-time voltage mode control to achieve near unity power factor for the CRM Flyback converters. Figure 8 shows the Ramp Generator with Feed-Forward compensation and THD optimization circuit for the constant on-time operation.Figure 8. Ramp GeneratorThe charging current of ramp generator is modulated following the squared FF voltage with line voltage compensation and the THD optimization scheme is implemented to compensate the harmonic distortion. ZCD and Enable FunctionIn CRM operation, when the power switch turns on, the inductor current increases linearly to the peak value. When the power switch turns off, the inductor current decreases linearly to zero. The zero current can be detected by the ZCD pin with the auxiliary winding of Flyback inductor.Figure 9 and Figure 10 show the ZCD block diagram and related waveforms. The ZCD block diagram provides zero current detection, voltage clamp and shutdown control functions. When the inductor current decreases to zero, the auxiliary winding voltage will turn from high to low. Once the ZCD voltage decreases to the threshold V ZCDT (1V, typ.), the controller will generate a signal for gate driver. The hysteresis voltage between the threshold V ZCDA (1.6V, typ.) and V ZCDT is designed to avoid mis-triggering. In order to prevent over voltage stress, the ZCD pin voltage is clamped at V ZCDH (4.8V, typ.) if the input voltage is too high from the auxiliary winding and the ZCD pin voltage is clamped at V ZCDL (0.6V, typ.) if the input voltage is lower than V ZCDL .RT7313Copyright © 2016 Richtek Technology Corporation.

DS7313-01 July 20166R ZCDFigure 9.ZCD Block DiagramThe RT7313 provides shutdown function to save power consumption in standby mode. When the ZCD pin is pulled lower than 250mV, the gate driver will be turned off and operate in standby mode with low quiescent current less than 600µA. Once the ZCD pin is released, the controller will be activated.The RT7313 also provides ZCD time-out detection function. If the controller runs at maximum frequency and there is no ZCD signal being detected after 4µs delay time, the PWM will be turned on for ZCD time-out detection.V V I V V V VFigure 10.

Start-Up Waveforms of VDD and I DD Figure 11 and Figure 12 show the equivalent start-up circuit and VDD waveform during start-up. In general, the start-up time (t start ) is required from system specification. The charging current (Ich VDD ) can be estimated by the following equation.VDD ON_THVDD startC V Ich = (8)t ⨯where C VDD is the capacitor connected between VDD and GND, V ON_TH is the power on threshold (16V typ.). The start-up resistor (R start ) connected between V CSIN and VDD should be able to support the charging current (Ich VDD ), start-up current (I DD_ST ) and leakage current (I leakage ) of C VDD before the VDD is supported by the auxiliary winding. The maximum start-up resistance can be calculated by the equation (9).Start DD_ST VDD leakageRwhere V IN ac_min is the minimum input voltage. Note that the start-up resistor must have adequate voltage rating for reliability. 2 resistors in series can be applied for most of applications.For example, the system required start-up time is 3sec, V IN ac_min = 75V and maximum I DD_ST = 20μA. If C VDD = 22μF is selected and the leakage current of C VDD can be ignored, the start-up resistor should be less than 772k Ω.The capacitor C FF is applied to filter out the input ripplevoltage. The corner frequency should be lower than line frequency (f line ). If the FF pin voltage is not flat, the PF and THD performance will be degraded.line FF1FF2FF1 < 0.1f (10)2(R // R )C π⨯⨯⨯Thermal ConsiderationsFor continuous operation, do not exceed absolutemaximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula : P D(MAX) = (T J(MAX) - T A ) / θJAwhere T J(MAX) is the maximum junction temperature, T A is the ambient temperature, and θJA is the junction to ambient thermal resistance.For recommended operating condition specifications, the maximum junction temperature is 125︒C. The junction to ambient thermal resistance, θJA , is layout dependent. For SOP-8 package, the thermal resistance, θJA , is 160︒C/W on a standard JEDEC 51-3 single-layer thermal test board. The maximum power dissipation at T A = 25︒C can be calculated by the following formula :P D(MAX) = (125︒C - 25︒C) / (160︒C/W) = 0.625W for SOP-8 packageThe maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA . The derating curve in FigureRT7313Copyright © 2016 Richtek Technology Corporation. All rights reserved. is a registered trademark of Richtek Technology Corporation.DS7313-01 July 20161313 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation.Figure 13. Derating Curve of Maximum PowerDissipation Layout ConsiderationsA proper PCB layout can abate unknown noise interference and EMI issue in the switching power supply. Please refer to the guidelines when designing a PCB layout for switching power supply.④The current path(1) from input capacitor, transformer, MOSFET, R CS return to input capacitor is a high frequency current loop. The path(2) from GD pin,MOSFET, R CS return to input capacitor is also a high frequency current loop. They must be as short as possible to decrease noise coupling and kept a space to other low voltage traces, such as IC control circuit paths, especially. Besides, the path(3) between MOSFET ground(b) and IC ground(d) is recommended to be as short as possible, too.④It is good for reducing noise, output ripple and EMI issue to separate ground traces of input capacitor(a), MOSFET(b), auxiliary winding(c) and IC control circuit(d). Finally, connect them together on input capacitor ground(a). The areas of these ground traces should be kept large.④Placing bypass capacitor for abating noise on IC is highly recommended. The capacitors C INV and C CS should be placed as close to controller as possible. ④In addition, apply sufficient copper area at the anode and cathode terminal of the diode for heat-sinking. It is recommended to apply a larger area at the quiet cathode terminal. A large anode area will induce high-frequency radiated EMI.NeutralFigure 14.

PFCG管理手册
PFCG管理员权限配置手册目录●目的： (2)●实现方法： (2)●配置步骤： (2)1.创建角色 (2)2.添加事务代码 (3)3.更改授权数据。
(4)1)限制二级管理员可以添加的T-CODE。
(5)2)限制二级管理员可以创建及修改的角色名称。
(5)3)对各公司的Company Code进行限制。
(5)4)对USER GROUP进行限制。
(6)文档更动历史目的：为了使各级分公司管理员可以只能管理该公司的权限和用户而不能对其他公司的权限和用户作修改，现将管理员权限的管理分为两层：1.最高管理员权限。
2.各级分公司管理员权限。
最高管理员权限：可以对所有的权限和用户进行更改和创建。
各级分公司管理员权限：允许该管理员只能创建及更改该公司的权限和用户，对于其他公司权限和用户则无权进行更改。
实现方法：可以通过对授权对象进行限制来达到限制分公司管理员权限的目的，方法如下：1．对T－CODE进行限制通过对T-CODE进行限制，可以实现分公司的管理员对添加的事务代码（T-CODE）进行限制，允许分公司管理员只能添加允许范围内的T-CODE。
2．对ROLE进行限制通过对ROLE进行限制，可以实现分公司的管理员对创建及修改的角色名称进行限制，允许分公司管理员只能创建及修改允许范围内的角色名称。
3．对Company Code进行限制通过对Company Code进行限制可以实现对分公司的限制，允许分公司管理员只能添加或管理该公司的权限及具体操作。
4．对USER GROUP进行限制通过对USER GROUP进行限制，可以实现分公司的管理员对用户管理进行限制，允许分公司管理员只能添加或修改允许范围内USER GROUP的用户。
配置步骤：1.创建角色为二级单位管理员创建角色（如：Y:TEST01）。
运行事务代码：PFCG2.添加事务代码添加事务代码（T-CODE）：SU01,PFCG,SU53。
在“菜单”栏（圈1）下点击“添加事务”（圈2），进入添加事务代码界面。

1总体描述
本文旨在描述SAP权限管理员使用PFCG工具对角色的建立和分配，以及对授权对象的增加和修改，本文的主要读者包括中石化ERP项目组的技术小组成员和权限管理员。
2创建普通角色：
2.1运行PFCG，输入角色名，例如：Z:TEST
角色名称创建角色
2.2点“创建角色”
菜单
2.3点“菜单”，给该角色分配事务码、报表等
事务
2.4点“事务”
输入要添加的事务代码，点“分配交易”
来自SAP菜单
2.5如果从SAP菜单选择一类事务，则点“来自SAP菜单”
选择相应的权限后，点“传输”
2.6点“权限”，详细设置该角色的授权对象、组织级别及参数值
权限
更改授权数据
2.7点“更改授权数据”
第四个菜单：实用程序-设置
“显示技术名称”打勾，点“设置”，则可显示授权对象名称和参数名称等
2.8 点BC_A->S_USER_GRP->CLASS 前面的铅笔，或者双击其值的区域
选择值
单击此处 技术名称
或双击此处
点此选择权限值
打勾选择保存
2.9点BC_A->S_USER_GRP->CLASS前面的铅笔，或者双击其值的区域
选择相应的权限值，保存
2.10把所有的权限都做正确设置，去掉黄色（参数）和红色（组织级别）
点“生成”
2.11点“生成”，生成参数文件
若仍有黄色或红色则会出现如下提示：
点“生成”即可
若该角色第一次生成则出现如下提示：
