DESCRIPTION

EVM3632S-PQ-00A evaluation board is based on MPS’S MPM3632S. The MPM3632S is a synchronous rectified, step-down Mini-Module regulator with built-in power MOSFETs, inductor and two capacitors. It offers a very compact solution with only input and output capacitors to achieve a 3A continuous output current with excellent load and line regulation over a wide input supply range. The MPM3632S operates in fixed 2.2MHz switching frequency with Constant-On-Time control which provides fast load transient response. Full protection features include output over voltage protection, over-current protection and thermal shut down. MPM3632S eliminates design and manufacturing risks while dramatically improving time to market. The MPM3632S is available in a space-saving LGA10 (3mmx3mmx1.45mm) package.. ELECTRICAL SPECIFICATION (1) Parameter Symbol Value Units Input Voltage V IN 12 V Output Voltage V OUT 3.3 V Output Current I OUT 3 A Notes: 1) For different Input/output voltage specs and different output capacitor/inductor may need change the application circuit parameters.
