PF7708B Powerforest

The PF7708B is a single-channel LED driver with a wide input voltage range of 9V to 30V and current mode control. It integrates a 1000mA/-1500mA MOSFET driver and dimming MOSFET in a small SOP-8 package. The device provides short LED, overcurrent, overtemperature, and overvoltage protections for applications such as LED backlights with low total cost.
