150kHz 3A BUCK DC-DC CONVERTER

AP3003

The AP3003 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 AP3003 requires a minimum number of external components to work.

A standard series of inductors, optimized for use with the AP3003 series, are available from several manufacturers. This feature greatly simplifies the design of switch-mode power supplies.

These ICs are available in TO-220-5 and TO-263-5 packages.
