EVHF900-P-00A 85VAC/60Hz~420VAC/60Hz, 13.5V/300mA;8V/50mA;8V/50mA Off-line Evaluation Board
The MPS EVHF900-P-00A is an evaluation board for bench characterisation of the device in its intended topology. It switches at 300 kHz.
The HF900 is a flyback regulator with a 900V MOSFET integrated, targeting high AC input voltage application.

Evaluation Board
Design Notes
- The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
- Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
- Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
- Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
