High Effeciency, Fast Transient, 2A, 16V Synchronous Step-down Converter

Overview

TopologyBuck Converter
Input voltage4.2-16 V
Output 11.2 V / 2 A
IC revision1.01

Description

The EV1492DS-00A is a fully integrated high frequency synchronous rectified step-down switch mode converter. It offers a very compact solution to achieve 2A continuous output current over a wide input supply range withexcellent load and line regulation. The MP1492 operates at high efficiency over a wide output current load range.

Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization.

Full protection features include OCP, OVP, UVP and thermal shut down.

The EV1492DS-00A requires a minimum number of readily available standard external components and is available in an 8-pin SOIC package.
