EVM3530-RF-01A 55V, 3A, Step-Down Power Module Demo Board DESCRIPTION FEATURES The EVM3530-RF-01A is based on MPSs Wide 4.5V to 55V Operating Input Range MPM3530 module. The MPM3530 is an easy- Wide Output Voltage Adjustable: 1V to 15V to-use, fully integrated, 55V input, 3A, step- Programmable Switching Frequency with down DC/DC power module. The MPM3530 External SYNC Function integrates a monolithic DC/DC converter, power External Soft Start (SS) inductor, input capacitors, and the necessary Over-Current Protection (OCP) resistors and capacitors in a compact QFN High Efficiency for Light-Load Operation package. This total power solution requires only a few external components. Over-Voltage Protection (OVP) and Thermal Shutdown Protection The MPM3530 uses peak-current-mode control Power Good (PG) Indication to regulate the output voltage. This module provides over-current protection (OCP) with Meet EN55022 Class B Emission valley-current detection, which is used to Operating Temperature Range: -40C to prevent current runaway. The MPM3530 also 85C has accurate and reliable over-voltage Available in a QFN-44 (12mmx10mmx4mm) protection (OVP) and auto-recovery thermal Package protection. An optional external soft start is available, and enable and power good indicator APPLICATIONS functions are provided. To increase efficiency, Telecom and Networking Systems the MPM3530 scales down the switching Industrial Equipment frequency automatically when load is light All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
