The HF920BGSE-P from Monolithic Power Systems is a fixed-frequency flyback controller with an integrated switch for isolated offline AC-DC conversion. It features a 900V breakdown rating, a 10V to 24V Vcc supply, a 4V start-up voltage, and up to 83% duty cycle. Delivering up to 9.5 W with switching frequencies up to 150kHz, it includes current limiting, over-load, over-temperature, and short-circuit protection in an 8-SOIC package.
- 900V breakdown rating supports high-voltage offline flyback designs with margin.
- Integrated switch simplifies isolated flyback power stages and reduces external parts.
- Up to 9.5 W output with switching frequencies up to 150kHz enables compact magnetics.
- Comprehensive protection set (current limiting, over-load, over-temperature, short circuit) improves reliability.
- -40°C to 125°C junction range suits demanding industrial environments.
Isolated Auxiliary Supplies
The 900V breakdown rating and integrated switch make the HF920BGSE-P well suited to isolated auxiliary bias supplies fed from high-voltage DC rails, where a compact flyback stage is required.
Industrial Metering and Control
With a -40°C to 125°C junction temperature range and up to 9.5 W output, this flyback controller fits isolated power stages in industrial instrumentation and control boards.
Smart Meter and Appliance Power
Fixed-frequency flyback operation with frequency control and up to 83% duty cycle supports compact isolated power for metering and appliance electronics.
Offline Standby Rails
