High-Efficiency, 8A, 18V, Synchronous Step-Down Converter
Session Titefor popup
The MP2238 is a high frequency, synchronous, rectified, step-down switch-mode converter. It offers a fully integrated solution to achieve an 8A continuous output current with excellent load and line regulation over a wide input supply range.
Constant-on-time (COT) control operation provides fast transient response. Full protection features include hiccup over-current protection and thermal shutdown.
The MP2238 requires a minimal number of readily available, standard, external components with a space-saving 12-pin QFN 2mmx3mm package.

EV2238-D-00A Evaluation Kit High-Efficiency, 8A, 18V, Step-Down Converter Evaluation Board
The EV2238-D-00A evaluation board is designed to demonstrate the capabilities of MPS’s MP2238, a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve 8A of continuous output current over a wide input range, with excellent load and line regulation.
Constant-on-time control operation provides very fast transient response and easy loop design, as well as very tight output regulation.
Full protection features include SCP, OCP, and thermal shutdown.
The MP2238 requires a minimal number of readily available, standard external components, and is available in a space-saving, 12-pin QFN (2mmx3mm) package.
