3-Channel Low Dropout RGB LED Driver

General Description

Features

^zInput Voltage Range : 2.8V to 5.5V

The RT9301 is a 3-Channel current source driver for RGB

LED. It is easy to be designed in applications that need

mixing RGB light source for multi-color output.

^zLow 60/45mV Dropout at 20/15mA

^zIndividual Current Setting by External Resistor

^zIndividual On/Off Control by Baseband MPU

^zUp to 50mA LED Bias Current

^zSimple LED Brightness Control

^z3% LED Current Matching

The RT9301 also provide users with great flexibility and

device performance. It uses a external resistor to set the

bias current for three LEDs, which are matched to 3%.

Users can adjust the output current from 2mAto 50mA by

setting the ISET resistor.

^zLow 0.1uA Shutdown Current

^zUVLO Protection

The RT9301 features very low dropout and under voltage

lockout protection. It is available in a space-saving TSOT-

23-8 package.

^zTiny TSOT-23-8 Package
