Monolithic Power Systems MP2312

Description

The MP2312 is a fully integrated high frequency synchronous rectified step-down switch mode converter. It offers very compact solutions to achieve 2.1A continuous output current over a wide input supply range with excellent load and line regulation. The MP2312 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.

Under voltage lockout is internally set as 4.6 V, An open drain power good signal indicates the output is within its nominal voltage range.

Full protection features include OCP and thermal shut down.

The converter requires minimum number of external components and is available in QFN16 (3x3mm) package.
