TNY278 IC Off Line Switcher Power Integrations DIP-7 TNY278

Product Overview

The TNY274 is an energy-efficient off-line switcher integrated circuit manufactured by Power Integrations. It incorporates a high-voltage power MOSFET, an oscillator, an ON/OFF control state machine, and a high-voltage switched current source onto a monolithic device to route and regulate power across isolated flyback power supplies. The device delivers selectable current limits through varying external bypass capacitor values, maintains a self-biased architecture that eliminates the need for a transformer bias winding, and is highly efficient for reducing system costs while delivering enhanced design flexibility in adapters, chargers, and standby power systems.
