Intelligent three-color LED driver
BU8770FV
Description
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.
Features
1) 128 steps PWM brightness control
for each three color independently
2) DC/DC converter for LED driving
3) Low consumption stand-by circuit
4) Small SSOP-B16 package
