RT9301
3-Channel Low Dropout RGB LED Driver
General Description
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.
The RT9301 also provide users with great flexibility and
device performance. It uses a external resistor to set the
www.DataSbheiaest4Ucu.crorment for three LEDs, which are matched to 3%.
Users can adjust the output current from 2mA to 50mA by
setting the ISET resistor.
The RT9301 features very low dropout and under voltage
lockout protection. It is available in a space-saving TSOT-
23-8 package.
