Краткое описание:
Automotive 65-V 4-A backlight buck LED driver with flexible dimming
Дополнительная информация
The LP8868W-Q1 is an AEC-Q100 qualified non-synchronous multi-topology LED driver with an integrated 5.2-A, 150-mΩ MOSFET. It operates from a wide input voltage range of 4.5 V to 65 V and supports buck, boost, and buck-boost topologies. The device features multiple dimming options including analog, PWM, hybrid, and flexible dimming with an inductive fast dimming (IFD) capability for high accuracy. It includes comprehensive protection features such as LED open/short protection, cycle-by-cycle current limit, and configurable thermal foldback.
