Monolithic Power Systems (MPS) EVHF500A-20-P-00A Controller Evaluation Board is designed to demonstrate the capabilities of the HF500A-20, a single-stage, isolated flyback power supply converter in AC/DC power module and adapter applications. The Monolithic Power Systems (MPS) HF500A-20 is a fixed-frequency, current-mode regulator with built-in slope compensation. It combines a 700V MOSFET and a full-featured controller into one chip for a low-power, offline, flyback switch-mode power supply. The device optimizes EMI performance, especially for radiated emission.
