Description

The ACE752D is a high efficiency step down DC-DC converter with adjustable current limit in compact

SOP-8/ESOP-8 packages, including an error amplifier, ramp generator, current comparator, slope

compensation, current sense and logic driver. It also integrates a current error amplifier to have a

constant voltage and constant current control. Peak current mode PWM control with external adjustable

compensation provides a stable and high efficient operation over a wide range of load currents. By

means of an on board current sense resistor and the availability of the current sense pins, a current limit

programming is very simple and accurate.

The internal robust DMOS transistor with a typical of 150 mΩ

assures high efficiency even at high output current level. The internal limiting current of typical value of

3.5 A, output short and over temperature protection, protect the device from accidental damage. The

internal fixed switching frequency of 120 kHz, and the SOP-8/ESOP-8 packages pin allow building an

ultra compact DC/ DC converter with a minimum board space.
