The HFC0300HS-LF-P from Monolithic Power Systems is a flyback controller for isolated offline AC-DC power supplies. It drives an external switch with a 700V breakdown rating, operates from an 8.2V to 20V Vcc supply at 65kHz, and includes soft start and frequency control. Comprehensive protections cover Over Load, Over Voltage, Over Temperature, Short Circuit, and UVLO across a -40°C to 125°C (TJ) range in an 8-SOIC package.
- Galvanically isolated flyback topology for safe offline designs.
- 700V breakdown voltage supports high-voltage input rails.
- External switch drive offers design flexibility.
- Integrated protections: Over Load, Over Voltage, Over Temperature, Short Circuit, UVLO.
- Wide -40°C to 125°C (TJ) operating range.
