The Power Integrations TOP253PN is a TOPSwitch®-HX offline flyback switcher with an integrated 700V switch, delivering up to 25 W in an isolated topology. Operating at 66kHz with 78% maximum duty cycle, it includes current limiting, over temperature, and over voltage protection. Housed in a 7-lead 8-DIP package, it operates from -40°C to 150°C junction temperature.
- Integrated 700V switch reduces external component count and simplifies flyback designs.
- 25 W output power suits compact isolated AC-DC supplies.
- 66kHz switching with 78% max duty cycle supports efficient conversion.
- Built-in current limiting, over temperature, and over voltage protection enhance reliability.
- -40°C to 150°C junction range enables use in demanding environments.
