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.
