產(chǎn)品介紹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. The ZL3202 includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload. 產(chǎn)品屬性FEATURES 產(chǎn)品特點 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 其他說明TYPICAL APPLICATIONS 產(chǎn)品應用 Cell Phones Handheld Computers and PDAs Digital Still Cameras Small LCD Displays 交易說明Please directly contact us, thank you！
