Description

ACE7353N develops a high efficiency synchronous step-down DC-DC converter capable of delivering

3A load current. The ACE7353N operate over a wide input voltage range from 4.5V to 40V and integrate

The ACE7353N adopts peak current control scheme. The switching frequency is adjustable from 500kHz

to 2.5MHz using an external resistor. The device also features ultra low quiescent operating to achieve

high efficiency under light load. And the internal soft-start limits inrush current during power on.
