The Monolithic Power Systems HFC0512GS-P is a fixed-frequency flyback controller for isolated AC-DC conversion. It drives an external switch with a 790V breakdown rating, operates from a 9V to 24V Vcc supply at 130kHz, and features a 15.5V start-up threshold plus soft start and comprehensive fault protection in a 7-lead 8-SOIC package.
- External-switch flyback architecture allows flexible MOSFET selection for varied power levels.
- 790V breakdown rating supports wide-input offline designs.
- Fixed 130kHz switching simplifies transformer and EMI filter design.
- Over load, OVP, OTP, and short circuit protection enhance reliability.
- -40°C to 125°C junction temperature range suits demanding applications.
Isolated Offline Power Supplies
The HFC0512GS-P is a fixed-frequency flyback controller driving an external switch, enabling flexible power scaling for isolated AC-DC supplies. Its 790V breakdown rating supports wide-input offline designs.
Adapters and Consumer Electronics
With a 130kHz switching frequency and 9V to 24V Vcc supply, this controller suits compact adapters requiring isolated output and soft start.
Industrial and Telecom Auxiliary Rails
Operating from -40°C to 125°C junction temperature, the HFC0512GS-P fits auxiliary power stages needing over load, over temperature, over voltage, and short circuit protection.
External-Switch Design Flexibility
Because the switch is external, designers can select the MOSFET to match target power levels while benefiting from the controller's integrated protection and soft start.
