MP2328C中文资料High-Efficiency, 28V, 2A, 450kHz, Synchronous Step-Down Converter with PG, SS, and Forced CCM数据手册MPS规格书

描述 Description

The MP2328C is a fully integrated, high-frequency, synchronous, rectified, step-down switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve 2A of continuous output current (IOUT) across a wide input voltage (VIN) range, with excellent load and line regulation. The MP2328C offers synchronous mode operation for high efficiency across the wide IOUT load range.

Constant-on-time (COT) control provides very fast transient response and easy loop design, as well as tight output regulation.

Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown.

The MP2328C requires a minimal number of readily available, standard external components. It is available in a space-saving SOT583 package.
