The HFC0511GS-P from Monolithic Power Systems is a fixed-frequency Flyback controller for isolated off-line power supplies. It drives an external switch and features a 700V breakdown rating, operating from a 9V to 24V Vcc supply at a 130kHz switching frequency. Frequency control and soft start support stable operation, while comprehensive protection—current limiting, over load, over power, over temperature, over voltage, short circuit, and UVLO—ensures reliable performance. Offered in a 7-lead 8-SOIC package with a -40°C to 125°C junction temperature range.

  • Fixed 130kHz Flyback controller enables predictable, compact isolated transformer designs.
  • 700V breakdown rating supports off-line operation with adequate voltage margin.
  • Comprehensive fault protection—current limiting, over load, over power, over voltage, over temperature, short circuit, and UVLO—improves system safety.
  • Frequency control and soft start deliver stable operation and controlled power-up.
  • Wide 9V to 24V Vcc range and -40°C to 125°C operation suit diverse isolated applications.

Isolated AC-DC Adapters

The HFC0511GS-P is a fixed-frequency Flyback controller driving an external switch, providing galvanic isolation for off-line adapters. Its 130kHz switching frequency and 700V breakdown rating support compact transformer designs.

Industrial Power Supplies

With a -40°C to 125°C junction temperature range and comprehensive protection including current limiting, over power, over voltage, and over temperature, this controller suits robust isolated industrial supplies.

Chargers and Auxiliary Supplies

Frequency control and soft start enable stable operation and controlled startup for isolated charger and bias supply designs. Over load and short circuit protection safeguard the system under fault conditions.

Telecom and Networking Bias Rails
