MP2322

1A, 3-22V, 5μA I_Q, Synchronous, Step-Down Converter in 1.5x2mm QFN

Datasheet

Description

The MP2322 is a synchronous, rectified, step-down, switch-mode converter with built-in internal power MOSFETs and high light-load efficiency. The MP2322 offers a very compact solution that achieves 1A of continuous output current with excellent load and line regulation over a wide input supply range.

The MP2322 switching edge is optimized for EMI reduction. Constant-on-time (COT) control provides seamless mode transition and a fast load transient response.

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

The MP2322 requires a minimal number of readily available, standard, external components and is available in a space-saving QFN-8 (1.5mmx2mm) package.
