概要

MPL

MPS のインダクタで性能を最適化済み

The MP2322A is a synchronous, rectified, step-down switch-mode converter with built-in internal power MOSFETs and high light-load efficiency. The MP2322A offers a very compact solution that achieves up to 1A of continuous output current (I_OUT) with excellent load and line regulation across a wide input voltage (V_IN) supply range.

The MP2322A's switching edge is optimized for EMI reduction. Constant-on-time (COT) control provides seamless mode transitions and a fast load transient response.

Full protection features include over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown.

The MP2322A requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-8 (1.5mmx2mm) package.
