The Power Integrations TOP253EN is a TOPSwitch-HX offline flyback switcher with an integrated power switch for isolated AC/DC conversion. It delivers up to 25 W with selectable 66kHz and 132kHz switching frequencies and a 78% maximum duty cycle. The 700V breakdown rating, current limiting, over temperature, and over voltage protection, and a -40°C to 150°C (TJ) range make it suitable for compact isolated supplies in a 7-SSIP package.
- Integrated power switch with 700V breakdown rating simplifies isolated flyback design.
- Selectable 66kHz and 132kHz frequencies let designers optimize transformer size versus losses.
- Up to 25 W output supports mid-power adapter and appliance supplies.
- Current limiting, over temperature, and over voltage protection reduce external circuitry.
- 7-SSIP exposed-pad package improves thermal performance in enclosed designs.
Mid-Power AC/DC Adapters
The TOP253EN delivers up to 25 W in an isolated flyback topology, suited to notebook adapters and set-top box supplies. The 700V breakdown rating and integrated switch simplify offline front-end design.
Consumer Electronics Power Supplies
With selectable 66kHz and 132kHz switching frequencies and a 78% maximum duty cycle, designers can balance transformer size against switching losses. Galvanic isolation keeps the output safe for user-accessible ports.
Industrial Control & Instrumentation
The -40°C to 150°C (TJ) operating range supports industrial environments. Built-in current limiting, over temperature, and over voltage protection reduce external protection circuitry in isolated flyback rails.
Appliance & White Goods
The 7-SSIP package with exposed pad aids thermal dissipation in enclosed appliance housings. The integrated switch and 700V rating provide a compact isolated flyback solution for control electronics.
