The HF920AGS-P from Monolithic Power Systems is a fixed-frequency off-line flyback switcher with an integrated switch and 900V breakdown rating. It operates from a 10V to 24V Vcc supply at 150kHz with up to 83% duty cycle, delivering galvanically isolated output. Comprehensive protections include current limiting, over temperature, over voltage, short circuit, and UVLO, with soft start and frequency control. Offered in a 14-SOIC (11-lead) package rated -40°C to 125°C.
- 900V breakdown voltage enables robust off-line operation with margin for high bus voltages.
- Integrated switch reduces external component count and simplifies flyback design.
- 150kHz fixed frequency with 83% max duty cycle supports compact magnetics.
- Comprehensive protection suite (current limiting, OVP, OTP, SCP, UVLO) improves reliability.
- -40°C to 125°C junction range suits demanding thermal environments.
Off-Line AC/DC Power Supplies
The 900V breakdown rating and integrated switch make the HF920AGS-P well suited to flyback off-line supplies that must withstand high bus voltages. The 150kHz fixed frequency and 83% max duty cycle support compact transformer design.
Isolated Auxiliary Supplies
Galvanically isolated flyback topology provides safe separation between primary and secondary, ideal for auxiliary bias rails in industrial systems.
High-Voltage Adapters
With a 900V Vds rating and integrated switch, the device handles elevated input voltages while soft start and frequency control simplify loop and EMI-conscious design.
Harsh-Environment Designs
The -40°C to 125°C junction temperature range supports reliable operation in demanding thermal environments, backed by over temperature and short-circuit protection.
