The Power Integrations TOP256YN is an isolated Flyback offline switcher from the TOPSwitch®-HX series with an integrated 700V switch, delivering up to 119 W. It offers selectable 66kHz and 132kHz switching frequencies with up to 78% duty cycle, and includes current limiting, over temperature and over voltage protection. Housed in a TO-220-7 formed-leads package and rated -40°C to 150°C (TJ), it targets higher-power isolated offline designs.
- Integrated 700V switch supports isolated Flyback designs up to 119 W with fewer external parts.
- Dual 66kHz/132kHz frequency options let designers trade off efficiency and magnetics size.
- Up to 78% duty cycle enables wide input-range operation.
- Current limiting, over temperature and over voltage protection enhance reliability.
- Wide -40°C to 150°C (TJ) rating suits demanding thermal environments.
High-Power Isolated Offline Supplies
With up to 119 W output and a 700V integrated switch, the TOP256YN suits isolated Flyback designs for higher-power adapters and embedded power stages where galvanic isolation is required.
Industrial and Instrumentation Power
The -40°C to 150°C (TJ) rating and selectable 66kHz/132kHz switching frequencies allow designers to balance efficiency and EMI across industrial power supplies.
Consumer Electronics and Set-Top Power
Up to 78% duty cycle and integrated switch reduce external component count, enabling compact isolated Flyback converters for consumer equipment.
Telecom and Networking Auxiliary Rails
Current limiting, over temperature and over voltage protection support reliable isolated bias generation in networking and telecom hardware.
