Краткое описание:
Automotive 65-V, 4-A multi-topology LED driver with inductive fast dimming
Дополнительная информация
The LP8868-Q1 is a non-synchronous multi-topology LED driver with an integrated 5.2-A, 150-mΩ MOSFET and a wide input voltage range of 4.5 V to 65 V. It supports buck, boost, and buck-boost topologies and features inductive fast dimming (IFD) for high-precision PWM and analog dimming. The device is designed for automotive applications, featuring spread spectrum for reduced EMI and a configurable switching frequency from 100 kHz to 2.2 MHz.
