The Power Integrations TOP234YN is an integrated offline switch IC belonging to the TOPSwitch-FX family. It is designed for flyback applications and comes in a TO-220-7B package, suitable for through-hole mounting.
This component features a high voltage rating of 700V and can deliver up to 75W of power. Its operating frequency ranges from 66kHz to 132kHz, with options for frequency jittering to reduce EMI and a half-frequency option for video applications. The device integrates several features to reduce system cost and improve design flexibility, including fully integrated soft-start, externally settable accurate current limit, and hysteretic thermal shutdown for automatic recovery.
Key electrical features include line under-voltage and overvoltage detection, line feed-forward with maximum duty cycle reduction, and regulation to zero load without dummy loading. It also supports remote ON/OFF capability and can be synchronized to a lower frequency. The operating temperature range is -40°C to 150°C (TJ).
The TOP234YN is designed for energy efficiency, utilizing cycle skipping to reduce no-load consumption and reduced consumption in remote off mode. Its robust design includes fault protection for current limiting, over temperature, and over voltage conditions.
