The Monolithic Power Systems HF920BGSE-Z is a fixed-frequency flyback offline switcher with an integrated 900V power switch for isolated AC-DC conversion up to 9.5 W. It operates at switching frequencies up to 150kHz with an 83% maximum duty cycle, running from a 10V to 24V Vcc supply with a 4V start-up threshold. Current limiting, over load, over temperature, and short circuit protection are built in, packaged in an 8-SOIC (7 leads) rated for -40°C to 125°C junction temperature.
- 900V integrated switch provides extra voltage margin for high-voltage isolated designs.
- Fixed-frequency operation up to 150kHz supports predictable EMI behavior.
- Compact 8-SOIC package suits space-constrained auxiliary supplies.
- Built-in current limiting, over load, over temperature, and short circuit protection enhance reliability.
- -40°C to 125°C junction rating supports demanding environments.
High-Voltage Isolated Supplies
The HF920BGSE-Z integrates a 900V switch in a flyback topology, enabling isolated AC-DC conversion up to 9.5 W in high-voltage input applications where margin above standard 650V devices is valuable.
Compact Auxiliary Bias Rails
With a 10V to 24V Vcc range and 4V start-up threshold, this device supports isolated housekeeping supplies in metering, appliances, and industrial controls.
EMI-Sensitive Designs
Fixed-frequency operation up to 150kHz with frequency control supports predictable switching behavior in noise-sensitive isolated supplies.
Robust Low-Power Conversion
Current limiting, over load, over temperature, and short circuit protection, combined with -40°C to 125°C junction rating, support reliable operation in demanding environments.
