The TOP256EN from Power Integrations is an offline Flyback switcher in the TOPSwitch®-HX series featuring an integrated 700V switch. It delivers up to 119 W with selectable 66kHz/132kHz switching and 78% maximum duty cycle. Protections include current limiting, over temperature, and over voltage. Packaged in a 7-SSIP with exposed pad, it operates from -40°C to 150°C junction temperature.
- Integrated 700V switch simplifies isolated Flyback designs and reduces external parts.
- Up to 119 W output supports medium-power offline applications.
- Selectable 66kHz/132kHz frequency enables efficiency and EMI tuning.
- Current limiting, over temperature, and over voltage protection enhance reliability.
- Wide -40°C to 150°C junction temperature range suits demanding environments.
