The TOP255EN from Power Integrations is part of the TOPSwitch-HX series. It is an isolated flyback offline switcher with an integrated switch, offering a 700V breakdown rating and up to 81W output. It operates at 66kHz or 132kHz with a 78% maximum duty cycle. Protections include current limiting, over temperature, and over voltage. Housed in a 7-SSIP exposed-pad package rated for -40°C to 150°C junction temperature.
- Integrated switch simplifies isolated flyback designs and reduces component count.
- 700V breakdown rating provides margin for high-line AC input transients.
- Delivers up to 81W for higher-power isolated applications.
- Selectable 66kHz or 132kHz switching frequency with 78% maximum duty cycle.
- Rated for -40°C to 150°C junction temperature for demanding environments.
