MP1519 Datasheet High Efficiency Charge Pump 4 White Led Driver

Manufacturer: Monolithic Power Systems

Overview: TM MP1519 1x, 1.5x, 2x High Efficiency Charge Pump 4 White LED Driver The Future of Analog IC Technology.

General Description

The MP1519 is a fully automatic driver for powering four white LEDs, with up to 4V forward voltage, from a single Li-Ion or three NiMH cells.

The driver performs all of the sensing and control to run the LEDs at an optimum charge pump ratio for efficiency without an expensive inductor.

The driver allows PWM operation to support brightness control.
