YB1303
Low Dropout LED Driver
Description
The YB1303 provides a simple solution for
driving three channels of any color LEDs
with current matching ability. The ultra low
dropout LED driver features higher peak
efficiency and very low shutdown current.
The LED current can be adjusted by an
external resistor or the control voltage. The
YB1303 can work independently or
combine with any boost converters which
need to have current matching function for
LED drivers. The YB1303 is available in
6-pin tiny SC70-6 package.
