Monolithic Power Systems MP1492DS-00A
High Effeciency, Fast Transient, 2A, 16V Synchronous Step-down Converter
Overview
| Topology | Buck Converter |
| Input voltage | 4.2-16 V |
| Output 1 | 1.2 V / 2 A |
| IC revision | 1.01 |
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.
