Monolithic Power Systems MP1492

2A, 4.2V-16V Input, Fast Transient Synchronous Step-down Converter

Overview

TopologyBuck Converter
Input voltage4.2-16 V
Output 11.2 V / 2 A
IC revision1.1

Description

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) controlmode provides fast transient response, eases loop stabilization, and operates with a low-cost electrolytic capacitor.

The MP1492 requires a minimum number of readily available standard external components and is available in an 8-pin SOIC ROHS compliant package.

Features

  • Wide 4.2V to 16V Operating Input Range
  • 2A Output Current
  • Adaptive COT for Fast TransientResponse
  • Low RDS (ON) Internal Power MOSFETs
  • Proprietary Switching Loss Reduction Technique
  • Programmable Switching Frequency
  • OCP, SCP, OVP, UVP Protection and Thermal Shutdown
  • Output Adjustable from 0.805V to 13V

Typical applications

  • Flat Panel Television and Monitors
  • Digital Set Top Boxes
  • Distributed Power Systems
