The AP2014 controller IC is designed to provide a low cost

synchronous Buck regulator for on-board DC to DC converter

applications. With today’s ASIC products requiring supply voltages

at 1.8V and lower, when the output current is as much as 3A and

the input voltage is at either 3.3V or 5V, traditional linear regulator

simply incurs too much loss within itself. The AP2014 together with

dual N-channel MOSFETs provide a low cost solution for such

applications. This device features an internal 200KHz oscillator

(400KHz for "A" version), under-voltage lockout for both Vcc and

Vc supplies, an external programmable soft-start function as well

as output under-voltage detection that latches off the device when

an output short is detected.

Applications

• Graphic Card

• Hard Disk Drive

• DDR memory source sink Vtt application

• Low cost on-board DC to DC such as 5V to 3.3V, 2.5V or 1.8V
