The HFC0300HS-LF-Z from Monolithic Power Systems is a Flyback offline switching controller for isolated AC-DC power conversion. It drives an external switch and offers a 700V breakdown rating, an 11.7V start-up threshold, and an 8.2V to 20V Vcc supply. Over load, over temperature, over voltage, and short circuit protections are included, with frequency control. It operates from -40°C to 125°C junction temperature in an 8-SOIC (7-lead) package.
- 700V breakdown rating — supports high-voltage offline flyback designs.
- External switch drive — allows power MOSFET selection matched to the application.
- Comprehensive protections (over load, over temperature, over voltage, short circuit) — enhances reliability.
- 8.2V–20V Vcc with 11.7V start-up — flexible bias design.
- Wide -40°C to 125°C junction range — suited to demanding thermal environments.
