Description

ACE735N develops a high efficiency synchronous step-down DC-DC converter capable of delivering

1.5A load current. The ACE735N operate over a wide input voltage range from 4V to 40V and integrate

The ACE735N adopts peak current control scheme. The switching frequency is 2MHz. Low output

voltage ripple and small external inductor and capacitor sizes are achieved with 2MHz switching

frequency.

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.
