EVHF500-30-P-00A HF500-30 Full Featured Flyback Regulator Evaluataion Board Evaluation Board

The HF500-30 is a fixed-frequency, current-mode regulator with built-in slope compensation.

Key Specifications

Features

• 700V/1.4 Integrated MOSFET
• Fixed-Frequency Current-Mode-Control Operation with Built-In Slope Compensation
• Frequency Foldback Down to fOSC(min) at Light Load
• Burst Mode for Low Standby Power Consumption
• Frequency Jittering for a Reduced EMI Signature
• Over-Power Compensation
• Internal High-Voltage Current Source
• VCC Under-Voltage Lockout (UVLO) with Hysteresis
• Programmable Input B/O and OVP
• VCC Over Voltage Protection (OVP)

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.
