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.
