BU8770FV Datasheet (LSI Computer Systems) - Intelligent three-color LED driver

BU8770FV, Intelligent three-color LED driver

BU8770FV is a smart LED driver developed for cellular phones.

This driver generates high-intensity LED driving voltage by stepping up VDD in DC/DC converter with using the clock of the built-in oscillator.

Each brightness of RGB color can be adjusted independently in 128 steps by PWM control.
