The HF500-15 is a fixed-frequency, current-mode regulator with built-in slope compensation. The HF500-15 combines a 700V MOSFET of high-avalanche ruggedness and a full-featured controller into one chip to create a low-power, offline, flyback, switch-mode power supply.
The EVHF500-15-S-00A evaluation board is designed to demonstrate the capabilities of MPS’s fixed switching frequency, multi-mode flyback regulator. It is designed for general-purpose offline power supplies.
The EVHF500-15-S-00A can meet EN55022 Class B conducted EMI requirements. It has multiple protection functions, including brown in/out, overload protection (OLP), over-voltage protection (OVP), short-circuit protection (SCP), cycle-by-cycle current limiting, and over-temperature protection (OTP).
The EVHF500-15-S-00A specification is listed in the table below.
