GENERAL DESCRIPTION
The ZCC1496A is a fully integrated, high
efficiency 2A synchronous rectified step
down converter. The
ZCC1496A operates
at high efficiency over a wide output current
load
range.
This
device
offers
two
operation modes, PWM control
and
PFM
Mode switching control, which
allows a
high efficiency over the wider range of the
load. The ZCC1496A
requires a
minimum
number
of readily
available
standard
external
components and is available in a
6-pin SOT23-6 compliant package.
