1 / 9 page ACE752D 120KHz 3.5A Buck DC-DC Converter VER 1.1 1 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. Features • Up to 2.1A/2.4Aoutput current • Input Under Voltage Lockout • Operating voltage can be up to 40V • 120 kHz Internal Jitter Frequency for lower EMI • Patent-Technique Constant Voltage and Constant Current Control. • Patent-Technique Output Voltage Compensation • Adjustable current limit • Over Temperature Protection • Small SOP-8/ESOP-8 Packages Application • Car Charger/Adaptor • Rechargeable Portable Devices • General-purpose step-down converters with adjustable current limit |
