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.
