AP1501

150KHZ, 3A PWM BUCK DC/DC CONVERTER

Description

The AP1501 is a fully integrated step-down DC/DC converter, with the

ability to drive 3A load without the need of additional driver

components. The AP1501 operates at a switching frequency of

150kHz enabling the use of small size filter components. As a result,

board space is reduced and BOM costs are lowered.

The AP1501 has integrated the shutdown function that allows standby

mode to be activated via an external logic signal input. The internal

compensation facilitates feedback control for line and load regulation

without the need of an external circuitry. The AP1501 has a built-in

Thermal shutdown and Current Limit function to prevent damage from

high operating temperature and high current operating to the output

switch.

Additional features include a guaranteed +/- 4% tolerance on the

output voltage under specified input and output load conditions, and

+/- 15% on oscillator frequency. The AP1501 offers both fixed and

adjustable output voltages. For fixed outputs the AP1501 supports

3.3V, 5.0V and 12V. The package options available are standard 5-

lead TO263 and TO220 packages.
