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.
