The Power Integrations LNK3792D-H004-TL is an isolated flyback switcher with an integrated 900V power switch and secondary-side synchronous rectification. It delivers up to 12W at 66kHz switching frequency, operating from an 85V to 265V Vcc supply. Over temperature and over voltage protection are included in a 14-lead SOIC package rated for -40°C to 105°C ambient temperature.
- Integrated 900V switch reduces external component count and simplifies design.
- Isolated flyback topology with secondary-side SR supports efficient low-power conversion.
- 12W output capability suits compact offline supplies.
- 66kHz switching frequency balances magnetics size and efficiency.
- -40°C to 105°C ambient range supports industrial environments.
