The Power Integrations TOP270EG is a TOPSwitch-JX offline switcher IC integrating the power switch for isolated Flyback designs up to 190 W. It features a 725V breakdown rating, 78% maximum duty cycle, and selectable 66kHz/132kHz switching with frequency control. Packaged in a 7-SSIP with exposed pad and formed leads, it includes current limiting, over load, over temperature, over voltage, and short circuit protection across a -40°C ~ 150°C junction range.
- Integrated switch enables higher-power isolated Flyback designs with fewer parts.
- 725V breakdown rating supports robust offline operation.
- Selectable 66kHz/132kHz frequency control aids transformer optimization.
- Comprehensive fault protection improves reliability.
- Wide -40°C ~ 150°C junction range suits demanding environments.
Higher-Power AC-DC Supplies
Delivering up to 190 W, the TOP270EG suits isolated Flyback power supplies where an integrated switch reduces design complexity.
Industrial Power Converters
The -40°C ~ 150°C junction range and 725V breakdown rating support isolated industrial power stages.
Appliance and Embedded Power
Selectable 66kHz/132kHz frequency control helps optimize transformer and EMI trade-offs in isolated Flyback designs.
Protected Power Rails
Over load, over voltage, over temperature, short circuit, and current limiting protection safeguard the system.
