产品详细介绍
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. The ZL3202 includes
under-voltage lockout, current limiting and thermal overload
protection preventing damage in the event of an output overload.
