资料介绍

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.
