ZXSC380
Single or multi cell LED driver solution
Description
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.
Features
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 for
single cell LED driving applications.
