The EVHF500A-20-P-00A is an evaluation board 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 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.

The HF500A-20 features a wide 100V_AC to 265V_AC input voltage (V_IN) range and a 12V/1.5A constant voltage output.

The HF500A-20 achieves low standby power consumption and high efficiency under full-load conditions. The HF500A-20 can pass EN55022/CISPR 22 Class B standards for both conducted emissions (CE) and radiated emissions (RE).

Full protection features include brownout (BO) protection, output short-circuit protection (SCP), overload protection (OLP), output over-voltage protection (OVP), and over-temperature protection (OTP).
