The HF920GS-P from Monolithic Power Systems is a fixed-frequency off-line flyback switcher with an integrated switch and 900V breakdown rating. It runs from a 10V to 24V Vcc supply at 150kHz with up to 83% duty cycle, delivering galvanically isolated output. Protections include current limiting, over load, over temperature, over voltage, short circuit, and UVLO, plus soft start and frequency control. Supplied in a 14-SOIC (11-lead) package rated -40°C to 125°C.
- 900V breakdown voltage provides margin for high off-line bus voltages.
- Integrated switch reduces external parts and simplifies flyback design.
- 150kHz fixed frequency with 83% max duty cycle supports compact magnetics.
- Broad protection suite including over load, OVP, OTP, SCP, and UVLO.
- -40°C to 125°C junction range suits demanding thermal environments.
Off-Line AC/DC Power Supplies
The 900V breakdown rating and integrated switch suit flyback off-line supplies exposed to high bus voltages. The 150kHz fixed frequency and 83% max duty cycle enable compact transformer design.
Isolated Bias Supplies
Galvanically isolated flyback topology provides safe primary-to-secondary separation for bias and auxiliary rails.
High-Voltage Adapters
With a 900V Vds rating and integrated switch, the device handles elevated input voltages, while soft start and frequency control ease loop and EMI-conscious design.
Harsh-Environment Designs
The -40°C to 125°C junction range supports reliable operation in demanding thermal environments, backed by over temperature, over load, and short-circuit protection.
