大功率升压型LED恒流驱动芯片常规系统应用简介-华之美半导体

大功率升压型 LED 恒流驱动芯片常规系统应用简介
序言
在当今全球能源紧缺的环境下，节约能源已成为大势所趋。同时，国家也大力倡导节能减排，已结束的 2008 年北京奥运会和即将落下帷幕的 2010 年上海世博会都不约而同地以绿色节能为主题，这就给中国 LED 照明产业的发展带来了巨大的历史机遇。大功率 LED 具有光效高、低功耗、寿命长、稳定性强、光色纯、安全性好、可控性佳等优点，正逐步取代以往的光源，开始广泛运用于全彩显示屏、交通信号灯、汽车车灯、背景光源、景观照明、特种工作照明等，成为照明领域的新一代绿色光源。据国内有关机构预测，在奥运、世博的强力带动下，中国 LED 照明市场规模将从 2007 年的 48.5 亿元快速增长至 2010 年的 98.1 亿元。有关专家分析认为，中国 LED 照明产业将在 2010 年前后迎来新的发展高峰。一般来说，大功率 LED 的功率在 1W 以上，目前比较常见的有 1W、3W、 5W、8W 和 10W。其被称为“绿色光源”，正朝着大电流（300mA～1.4A）、高效率（60～120lm/W）、亮度可调的方向发展。然而，大功率 LED 的发光强度是由流过 LED 的电流决定的，电流过强会引起 LED 的衰减，电流过弱会影响 LED 的发光强度，因此 LED 驱动需要提供恒流电源，以保证大功率 LED 使用的安全性，还需要满足预期的亮度要求，并保证各个 LED 亮度、色度的一致性。所以，传统上用于驱动灯泡(钨丝)、日光灯、节能灯、钠灯等光源的电源并不适合直接驱动大功率 LED。用市电驱动大功率 LED 也需要解决降压、隔离、PFC（功率因素校正）和恒流问题，还需有较高的转换效率。目前，市场上有上千款关于大功率 LED 恒流驱动的专用芯片，国内有广鹏 (ADDtek)、点晶(SITI)、晶锜(SCT)、华润矽威(PT)，国外有美国的超科(Supertex)、德州仪器（TI）、美信、国半、英国的捷特科（Zetex）等知名厂家。大多专用芯片采用迟滞型转换器，低电压输入范围，可升压、可降压、PWM 控制、功率开关可内置或外置、输出电流可以达到 1.5A，内置过压、欠压、短路和温度保护电路等。华之美半导体有限公司提供专为 LED Lighting 优化的恒流驱动

Functional Description Figure1IX9907 Typical Application2.1 Soft StartOnce the main input voltage is applied, a rectified voltage will appear across C I N. V CC capacitor (C VCC) will be charged during the power-up phase of operation through an external transistor. Once V CC reaches V VCC_on (typically 18V), the device will initiate a soft-start sequence. This is intended to minimize the electrical stresses on the device’s MOSFET power switch, D OUT, D VCC, and the transformer. The soft-start operates as shown in Figure2. The duration of this soft-start is 12mS nominal and steps V CS, the current sense voltage, to four values, as shown.Figure2Start-Up2.2 Normal OperationBecause the IX9907 employs quasi-resonant operation, its PWM switch-on is set by the zero crossing of the auxiliary winding voltage, and the switch-off is set by the current sense voltage.2.2.1Zero Crossing & Switch-On Determination The application example in Figure 1 shows that the voltage from the auxiliary winding is connected to the zero crossing pin, ZCV , through an RC network. This network provides a delay so that switch-on can occur at a voltage valley, thus enhancing efficiency. The required time delay, ∆t, should be approximatelyone-fourth of the oscillation period (determined by the inductance of the transformer’s primary and thedrain-source capacitance of the built-in power switch MOSFET) minus the propagation delay from zero-cross detect to power switch-on, t delay .This time delay, ∆t, should be matched by adjusting the RC network.After the power switch is turned off, its V DS will show some oscillation. This will also show on the ZCV input. T o avoid a mis-triggered switch turn-on, a ringing suppression circuit is implemented. The suppression time has two values that depend on the voltage at ZCV . If V ZCV is greater than 0.7V , then the time is 2.5μs nominal. If V ZCV is less than 0.7V , then the time is 42μs nominal. T urn-on of the power switch cannot occur during the suppression time, but does occur after a zero-crossing is detected. In the case of a missed zero-crossing, a maximum off-time isimplemented. After the power switch has been off for 42μs nominal (t offMax ), it is turned back on.2.2.2Switch-Off DeterminationIn the application circuit the primary current is sensed by R CS . The voltage across this resistor, V CS , isapplied to the CS input of the device. It is processed internally (V CSI N T = V CS(3) + 0.7V), and compared to the voltage at the VR pin, which is a scaled version of the rectified line voltage. When V CSI N T > VR, the power switch is turned off.Leading-edge blanking is used to prevent a false trigger caused by the voltage spike across R CS at the moment of power switch turn-on. This blanking time, t BLKCS , is nominally 450nS. T o prevent transformer saturation, a maximum on-time circuit is implemented. Max on-time for the power switch is 30μs nominal.2.2.3Foldback Point CorrectionWhen the AC line voltage increases, the power switch on-time decreases, which increases the operating frequency. As a result, with a constant primary current limit, the output power increases. T o provide output power regulation with respect to line voltage, theinternal foldback point correction circuit varies the V CS limit. The V CS limit is decreased in response to an increase in AC line voltage. The relationship between V CSMax and V I N is shown in Figure 3.Figure 3V CSMax vs. V IN∆t tOSC 4----------t delay –=t RC C ZCV R ZCV 1R ZCV 2---------------∙=The variation in AC line voltage is sensed by way of the auxiliary winding and an internal clamp and current sense circuit. When the power switch is on, a negative voltage proportional to the line voltage is coupled to the auxiliary winding; the IX9907 will hold the ZCV pin very close to ground during this time. The line voltage is thus sensed indirectly through the current in R ZCV1. This current is given by:The device uses I ZCV to vary the V CS limit as shown in Figure4. The actual implementation is digital and is shown below.Figure4V CS vs. I ZC2.2.4Protection FunctionsThe IX9907 provides comprehensive protection features. They are summarized in the table below:OUTPUT OVER-VOLT AGEDuring the power switch off-time the auxiliary winding voltage (V AUX) will swing positive and in proportion to the secondary voltage. V AUX is connected to ZCV through a resistor divider. If the voltage at ZCV exceeds a preset threshold (V ZCVOVP) for longer than the blanking time (t ZCVOVP), then the IC is latched off. SHORTED WI N DI N GIf the voltage at CS exceeds a preset threshold(V CSSW) during the power switch on time the device is latched off.OVER-TEMPERA TUREIf the die temperature exceeds 140°C, then the device will enter the Auto-Restart Mode.V CC OVER-VOL T AGE / U N DER-VOL T AGEThe IX9907 continuously monitors the V CC voltage. In case of an over-voltage event, the power switch is turned off and V CC will begin to fall. Once V CC goes below V CCoff (10.5V nominal), and is recharged up to V CCon (18.0V nominal), the device initiates a newsoft-start. For an under-voltage event the operation is the same except that the sequence begins withV CC < V CCoff so the power switch is off and V CC starts to be charged through an external transistor. This operation describes the Auto-Restart Mode.During Latch-Off Mode, the line voltage must be turned off and on again to begin normal operation.I ZCVV IN Na∙R ZCV1Np∙----------------------------=Action Taken Output O v er-V oltage Power Switch Latched Off Shorted W inding Power Switch Latched Off O v er-T emperature Auto-Restart ModeV CC O v er-V oltage Power Switch Latched Off V CC Under-V oltage Auto-Restart Mode3.

The SL221 is an open-loop peak current mode control LED driver IC. The SL221 can be programmed to operate in either a constant frequency or constant off-time mode. It includes an 8.0 - 550V linear regulator which allows it to work from a wide range of input voltages without the need for an external low voltage supply. The SL221 includes a PWM dimming input that can accept an external control signal with a duty ratio of 0 - 100% and a frequency of up to a few kilohertz. It also includes a 0 - 250mV linear dimming input which can be used for linear dimming of the LED current. The SL221 is ideally suited for buck LED drivers. Since the SL221 operates in open loop current mode control, the controller achieves good output current regulation without the need for any loop compensation. PWM dimming response is limited only by the rate of rise and fall of the inductor current, enabling very fast rise and fall times. The SL221 requires only three external components (apart from the power stage) to produce a controlled LED current making it an ideal solution for low cost LED drivers.

GND GATE
Ground return for all internal circuitry. This pin must be electrically connected to the ground of the power train. This pin is the output GATE driver for an external N-channel power MOSFET. This is the PWM dimming input of the IC. When this pin is pulled to GND, the GATE driver is turned off. When the pin is pulled high, the GATE driver operates normally. This is the power supply pin for all internal circuits. It must be bypassed with a low ESR capacitor to GND (≥0.1μF). This pin is the linear dimming input and sets the current sense threshold as long as the voltage at the pin is less than 250mV (typ). This pin sets the oscillator frequency. When a resistor is connected between ROSC and GND, the SL222 operates in constant frequency mode. When the resistor is connected between ROSC and GATE, the IC operates in constant off-time mode.
