Monolithic Power Systems (MPS) EV5470B-L-00A Evaluation Board

Monolithic Power Systems (MPS) EV5470B-L-00A Evaluation Board is designed to evaluate the performance of the MP5470B power management solution, which integrates four high-efficiency, step-down DC/DC converters. This converter with Constant-on-Time (COT) control provides a fast transient response. The MP5470B full protection features include Under-Voltage Lockout (UVLO), Over-Current Protection (OCP), and thermal shutdown. This converter's power-on/-off sequence can also be configured via the MTP. The EV5470B-L-00A board is ideal for enterprise SSD, NVDIMM, DSLR, FPGA-based design, and general 12V power systems.
