Product 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.

24V, High Current Synchronous Step-Down Converter Evaluation Board

The EV2312-Q-00A is an evaluation board for the MP2312, a high efficiency monolithic synchronous step-down converter.

The Evaluation Board can deliver 2.1A continuous load current from a 6V to 24V input with excellent load and line regulation.

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

The Evaluation Board can be turned on or shut down via a remote ON/OFF input that is reference to ground. This input is compatible with popular logic devices.
