ZXSC380: 18mA single cell LED boost driver with internal switch

The ZXSC380 is a highly integrated single or multi cell LED driver 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 ZXSC380 provides a simple to use, low cost, space saving and easy to layout solutions.
The ZXSC380 uses a PFM control technique to drive an internal switching transistor which
has 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 typical.
The ZXSC380 is offered in the space saving SOT23 package or in die form, offering an
excellent cost vs performance solution forsingle cell LED driving applications.
