UM1360 Datasheet (Union Semiconductor) - Hysteretic Buck High Brightness LED Driver

UM1360, Hysteretic Buck High Brightness LED Driver

The UM1360 is a PWM step-down converter with internal power switch, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage.

The UM1360 can drive up to 10 series connected LEDs.

The device operates from an input supply between 6V a
