MP2332H 1.2MHz Synchronous Step-Down Converter Monolithic Power Systems (MPS) MP2332H 1.2MHz Synchronous Step-Down Converter is a fully integrated, high-frequency, rectified, switch-mode converter with internal power MOSFETs. The compact solution achieves 2A continuous output current with excellent load/line regulation over a wide input range. The MP2332H uses synchronous mode operation for higher efficiency over the output current load range. Constant-on-time (COT) control operation provides a very fast transient response, easy loop design, and very tight output regulation.
