MP1492

2A, 4.2V-16V Input, Fast Transient

Synchronous Step-down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP1492 is a fully integrated, high–

efficiency 2A synchronous rectified step-down

converter. The MP1492 operates at high

efficiency over a wide output current load range.

Adaptive Constant-On-Time (COT) control

mode provides fast transient response, eases

loop stabilization, and operates with a low-cost

electrolytic capacitor.

•

Wide 4.2V to 16V Operating Input Range

2A Output Current

Adaptive COT for Fast Transient

Response

Low R_DS(ON) Internal Power MOSFETs

Proprietary Switching Loss Reduction

Technique

Programmable Switching Frequency

OCP, SCP, OVP, UVP Protection and

Thermal Shutdown

•

The MP1492 requires a minimum number of

readily available standard external components

and is available in an 8-pin SOIC ROHS

compliant package.

•

Output Adjustable from 0.805V to 13V

APPLICATIONS

•

Digital Set Top Boxes

Flat Panel Television and Monitors

Distributed Power Systems
