The TOP259EN from Power Integrations is an isolated flyback offline switcher with an integrated 700V switch, part of the TOPSwitch®-HX series. It delivers up to 238W with selectable 66kHz/132kHz switching and up to 78% duty cycle. Protection includes current limiting, over temperature, and over voltage. It is housed in a 7-SSIP (6-lead) exposed-pad package rated for -40°C to 150°C junction temperature, suited to higher-power isolated offline supplies.
- Integrated 700V switch in a flyback topology simplifies isolated offline designs.
- Up to 238W output supports higher-power isolated supplies.
- Selectable 66kHz/132kHz switching and 78% maximum duty cycle offer transformer design flexibility.
- Current limiting, over temperature, and over voltage protection enhance reliability.
- -40°C to 150°C junction temperature range and exposed-pad package aid thermal performance.
