The Monolithic Power Systems HF920AGSE-Z is a fixed-frequency offline flyback switcher with an integrated switch and 900V breakdown voltage. It delivers galvanically isolated output from a 10V to 24V Vcc supply, switching at 150kHz with up to 83% duty cycle. Comprehensive fault protection and soft start support dependable AC-DC conversion in an 8-SOIC package.
- 900V breakdown voltage provides ample margin for offline flyback designs.
- Integrated switch reduces external component count and simplifies isolated supply design.
- Fixed 150kHz frequency control with soft start enables predictable, stable operation.
- Comprehensive fault protection including current limiting, over voltage, over temperature, short circuit, and UVLO.
- -40°C to 125°C junction temperature range supports demanding environments.
AC-DC Power Adapters
The 900V breakdown rating and integrated switch make this flyback converter well suited for offline adapters requiring robust voltage margin and isolated output.
Industrial Auxiliary Supplies
With a -40°C to 125°C junction temperature range and comprehensive fault protection, it supports reliable isolated bias rails in industrial systems.
Standby and Housekeeping Power
