LM5116宽范围同步降压控制器概述该LM5116是一个同步降压控制器，适用于高输入电压或宽输入电压的环境中。

其控制方式是电流模式控制，该控制方式是利用一个模拟出来的电流斜坡。

电流模式控制提供了固有的线路前馈，以周期电流限制和易于循环的环路补偿。

电流模式控制提供固有的线性前馈，周期性循环的电流限制以及环路补偿。

仿真控制斜坡的使用可以减少脉宽调制电路的噪声灵敏度，是高输入电压应用中实现小占空比的可靠控制所必需的。

其工作频率可编程，从50kHz 至1MHz。

LM5116是驱动外部高边和低边的NMOS电源开关，这两个MOS管有自适应的死区时间控制。

可由用户选择二极管仿真的模式使芯片在轻负载时能够提高不连续工作模式的效率。

低静态关断电流就能使芯片不工作，并消耗总输入电流中的10μA。

其它特点包括一个高压偏置调节器、能自动切换到外部偏置以提高效率、热关断、频率同步、周期性限流、以及自适应线性欠压锁定。

该芯片选用TSSOP-20的封装，具有一个额外的焊盘以增加散热，这种封装方式在大功率模式下是十分有效的。

特色仿峰值电流模式输入电压范围可达100V低关断电流能驱动标准或逻辑级的MOS管栅极驱动电流可高达3.5A自由运行或同步操作到1MHz可选择的二极管仿真模式输出电压范围1.215V——80V电压基准精度为1.5%可编程限流可编程软启动可编程的线性欠压锁定自动切换到外部偏置电压TSSOP-20EP裸露焊盘热关断典型电路引脚名称描述1 VIN 芯片电源电压，输入电压2 UVLO 如果UVLO引脚的电压低于1.215V，调节器会进入待机模式（VCC调节器工作，开关驱动电路不工作）。

如果UVLO引脚电压高于1.215V，这个调节器正常工作。

可以通过外部分压器来设置欠压关断的阈值。

当EN引脚为高时，这个引脚存在一个固定的5μA上拉电流。

在工作在电流限制模式时，UVLO会每隔256个时钟周期被拉到地。

LM341/LM78MXX Series3-Terminal Positive Voltage RegulatorsGeneral DescriptionThe LM341and LM78MXX series of three-terminal positive voltage regulators employ built-in current limiting,thermal shutdown,and safe-operating area protection which makes them virtually immune to damage from output overloads.With adequate heatsinking,they can deliver in excess of 0.5A output current.Typical applications would include local (on-card)regulators which can eliminate the noise and de-graded performance associated with single-point regulation.Featuresn Output current in excess of 0.5A n No

Performance Characteristics(Continued)Design ConsiderationsThe LM78MXX/LM341XX fixed voltage regulator series has built-in thermal overload protection which prevents the de-vice from being damaged due to excessive junction tem-perature.The regulators also contain internal short-circuit protection which limits the maximum output current,and safe-area pro-tection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is in-creased.Although the internal power dissipation is automatically lim-ited,the maximum junction temperature of the device must be kept below +125˚C in order to meet data sheet specifica-tions.An adequate heatsink should be provided to assure this limit is not exceeded under worst-case operating condi-tions (maximum input voltage and load current)if reliable performance is to be obtained).1.0Heatsink ConsiderationsWhen an integrated circuit operates with appreciable cur-rent,its junction temperature is elevated.It is important to quantify its thermal limits in order to achieve acceptable per-formance and reliability.This limit is determined by summing the individual parts consisting of a series of temperature rises from the semiconductor junction to the operating envi-ronment.A one-dimension steady-state model of conduction heat transfer is demonstrated in The heat generated at thedevice junction flows through the die to the die attach pad,through the lead frame to the surrounding case material,to the printed circuit board,and eventually to the ambient envi-ronment.Below is a list of variables that may affect the ther-mal resistance and in turn the need for a heatsink.R θJC (Component Variables)R θCA (Application Variables)Leadframe Size &Material Mounting Pad Size,Material,&LocationNo.of

LM78MXX/LM341XX regulators have internal thermal shutdown to protect the device from over-heating.Under all possible operating conditions,the junction temperature of the LM78MXX/LM341XX must be within the range of 0˚C to 125˚C.A heatsink may be required depending on the maxi-mum power dissipation and maximum ambient temperature of the application.To determine if a heatsink is needed,the power dissipated by the regulator,P D ,must be calculated:I IN =I L +I GP D =(V IN −V OUT )I L +V IN I Gshows the voltages and currents which are present in the circuit.The next parameter which must be calculated is the maxi-mum allowable temperature rise,T R (max):θJA =TR (max)/P D If the maximum allowable value for θJA ˚C/w is found to be ≥60˚C/W for TO-220package or ≥92˚C/W for TO-252pack-age,no heatsink is needed since the package alone will dis-sipate enough heat to satisfy these requirements.If the cal-culated value for θJA fall below these limits,a heatsink is required.As a design aid,Table 1shows the value of the θJA of TO-252for different heatsink area.The copper patterns that we used to measure these θJA are shown at the end of the Application Note Section.reflects the same test results as what are in the Table 1shows the maximum allowable power dissipation vs.ambi-ent temperature for theTO-252device.shows the maximum allowable power dissipation vs.copper area (in 2)for

片的地线及其它小信号的地线分头接到 Bulk 电容的地端。 OVP 引脚 OVP 引脚走线尽可能短，且 RSET 电阻需要尽量靠近 OVP 引脚。OVP 引脚走线不能靠近 DRAIN 引脚走线以及 SW 引脚走线，如果有条件，可用地线将 OVP 引脚包围。变压器次级、输出电容的环路面积，以减小 EMI 辐射。 DRAIN 引脚增加 DRAIN 引脚的铺铜面积以提供芯片的散热能力。 NC 引脚 NC 脚必须悬空以保证芯片引脚间距满足爬电距离。
