ZXLD381, SINGLE OR MULTI CELL LED DRIVER SOLUTION

A Product Line of Diodes Incorporated ZXLD381 SINGLE OR MULTI CELL LED DRIVER SOLUTION Summary The ZXLD381 is a single cell LED driver designed for applications where step-up voltage conversion from a very low input voltage is required.

These applications mainly operate from 1.5V or 1.2V cells.

The IC generates constant current pulses that are ideal for driving single or multiple LEDs over a wide range of operating voltages.

The ZXLD381 uses a PFM control technique to drive an internal switchin
