The TOP256PN from Power Integrations is a Flyback offline switcher in the TOPSwitch®-HX series, integrating the power switch for a compact, isolated AC-DC conversion solution. It offers a 700 V breakdown rating, 66 kHz switching frequency, 78% maximum duty cycle, and up to 34 W output power. Built-in current limiting, over temperature, and over voltage protection support robust operation across a -40°C to 150°C junction temperature range in an 8-DIP package.
- Integrated power switch reduces external component count and simplifies flyback design.
- 700 V breakdown voltage supports universal AC input margins.
- Built-in current limiting, over temperature, and over voltage protection enhance reliability.
- Wide -40°C to 150°C junction temperature range suits demanding thermal environments.
- 66 kHz switching frequency and 78% max duty cycle enable compact, efficient isolated supplies up to 34 W.
Compact AC-DC Adapters
The TOP256PN's integrated switch and 700 V breakdown rating make it well suited for compact flyback adapters operating from universal AC mains, delivering up to 34 W with a simple, low-component-count design.
Standby and Auxiliary Supplies
