The HF920BGS-Z from Monolithic Power Systems is an isolated flyback AC-DC converter with an integrated switch and a 900V breakdown voltage rating. It operates from a 10V to 24V Vcc supply with a 4V start-up threshold, supports switching frequencies up to 150kHz, and delivers up to 10W. Housed in a 14-lead SOIC package, it includes current limiting, over load, over temperature, and short circuit protection for robust offline power designs.
- 900V breakdown voltage provides high-voltage margin for offline flyback designs.
- Integrated switch reduces external component count and simplifies layout.
- Comprehensive protection suite including current limiting, over load, over temperature, and short circuit.
- Wide -40°C to 125°C (TJ) operating range supports demanding environments.
- Fixed-frequency operation up to 150kHz with 83% maximum duty cycle.
Offline AC-DC Power Supplies
The HF920BGS-Z is an isolated flyback controller with an integrated switch and 900V breakdown rating, making it well suited for offline AC-DC conversion where high voltage tolerance is required. Its 10W power capability fits auxiliary and low-power supply rails.
Industrial Control Bias Supplies
With an operating temperature range of -40°C to 125°C (TJ), this device supports industrial environments. The integrated switch reduces external component count, while current limiting and over temperature protection safeguard the design.
Home Appliance Power Modules
