MPM3530GRF

MPM3530GRF is an easy-to-use, fully integrated, 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 over-current protection (OCP) with valley-current detection, which is used to prevent current runaway. To increase efficiency, the MPM3530 scales down the switching frequency automatically when the load is light. Typical applications include industrial power systems, diagnostic machines/test equipment, distributed power systems, telecom and networking systems.
