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
