Description

The ACE2596 series of regulators are fixed frequency PWM buck (step-down) DC/DC converter,

capable of driving a 3A load with excellent line and load regulation. These regulators include internal

frequency compensation and a fixed frequency oscillator so that they are easy to use. A system adopting

ACE2596 requires a minimum number of external components to work.

A standard series of inductors, optimized for use with the ACE2596 series, are available from several

manufacturers. This feature greatly simplifies the design of switch-mode power supplies.

These ICs are available in TO-263-5 packages.
