The TOP256GN-TL from Power Integrations is a TOPSwitch®-HX offline switching IC implementing an isolated flyback topology with an integrated power switch rated to 700 V breakdown. It delivers up to 34 W at a 66 kHz switching frequency with a 78% maximum duty cycle. Current limiting, over temperature, and over voltage protection are built in. The device is rated for junction temperatures from -40°C to 150°C and is supplied in an 8-SMD (7 leads) gull-wing package.
- Integrated 700 V switch reduces external component count in flyback designs.
- 34 W output suits compact isolated offline supplies.
- 78% max duty cycle and 66 kHz frequency simplify transformer design.
- Current limiting, over temperature, and over voltage protection built in.
- Wide -40°C to 150°C junction temperature range for demanding environments.
