产品介绍The ZL3202 is a step-up converter designed for driving up to 39 white LEDs (13strings of 3 LEDseach) from a 5V system rail. The ZL3202 uses a current mode, fixed frequency architecture to regulate the LED current, which is measured through an external current sense resistor. Its low 104mV feedback voltage reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition.产品属性The ZL3202 includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload.使用方法使用方法：具体的使用方法请仔细阅读说明书，或者是咨询专业人士。使用技巧使用方法：具体的使用方法请仔细阅读说明书，或者是咨询专业人士。主要特点2.5V to 6V input voltage Range ■ On Board Power MOSFET ■ Drives up to 39 White LEDs at 5V input ■ Up to 92% Efficiency ■ Over 1MHz Fixed Switching Frequency ■ Open Load Shutdown ■ Low 104mV Feedback Voltage ■ Soft-Start/PWM Dimming ■ UVLO, Thermal Shutdown ■ Internal 1.3A Current Limit 注意事项注意事项：具体的注意事项请仔细阅读说明书，或者是咨询专业人士。其他说明Cell Phones ■ Handheld Computers and PDAs ■ Digital Still Cameras ■ Small LCD Displays 交易说明如果有需要可以来电咨询！
