Краткое описание:
High-Efficiency LED Backlight Driver with 4 Channels and I2C Interface
Дополнительная информация
The LP8553 is a white LED driver with an integrated boost converter and four adjustable current sinks. It supports an input voltage range of 2.7V to 22V and provides adaptive output-voltage control to minimize power consumption. The device features 8-bit current resolution and up to 13-bit PWM resolution with optional dithering. It utilizes a proprietary phase-shift PWM control to reduce peak current and eliminate audible noise.
