MPM3530 Step-Down Power Module

Monolithic Power Systems’ MPM3530 is an easy-to-use, fully integrated, 55 V input, 3 A, step-down, DC/DC power module. The MPM3530 integrates a monolithic DC/DC converter, power inductor, input capacitors, and the necessary resistors and capacitors in a compact QFN package. The total power solution only requires a minimal number of external components.

The MPM3530 adopts a peak-current-mode control architecture with a fast transient response. This module provides overcurrent protection (OCP) with valley-current detection, which is used to prevent current runaway. The MPM3530 also has accurate and reliable overvoltage protection (OVP) and auto-recovery thermal protection. An optional external soft start is available, and enable and power good indicator functions are provided. To increase efficiency, the MPM3530 scales down the switching frequency automatically when the load is light.
