ACE2596
150KHz 3A Buck DC-DC Converter
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.
