MP2332C 650kHz Synchronous Step-Down Converter Monolithic Power Systems (MPS) MP2332C 650kHz Synchronous Step-Down Converter is a fully integrated, high-frequency, switch-mode converter with internal power MOSFETs. The MP2332C offers a very compact solution that achieves 2A of continuous output current with excellent load/line regulation over a wide input range. The MP2332C uses synchronous mode operation for higher efficiency over the output current load range. The constant-on-time (COT) control scheme of the MP2332C provides a very fast transient response, easy loop design, and tight output regulation.
