Overview

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 switching transistor which a low saturation resistance.
This ensures high efficiency, even for input voltages as low as 1V.
The IC can start up under full load and operates down to an input voltage of only 0.
9V.
The ZXLD381 is offered in the space saving SOT23 package or in die form, offering an excellent cost vs performance solution for single cell LED driving applications.
Features • 85% Efficiency • User adjustable output current • Single cell operation (0.
9V minimum) • Low saturation voltag...
