GENERAL DESCRIPTION
The ZCC1496
is a fully integrated, high
efficiency 2A synchronous rectified step
down converter. The ZCC1496
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 ZCC1496
requires a minimum
number of readily available standard
external components and is available in a
6-pin SOT23-6 compliant package。
