UM1350 Datasheet (Union Semiconductor)

UM1350, LED Lighting Driver

The UM1350 is capable of driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage.

This step-down converter provides an externally adjustable output current of up to 350mA from an input supply between 6V and 30V.

It can even reach 8 watts of out
