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.
