The Power Integrations TinySwitch®-4 series TNY290KG is an offline switcher IC for flyback power supply designs. This component integrates a 725V power MOSFET with a PWM controller, oscillator, fault protection, and other control circuitry within a single 12-ESOP package. It operates with a switching frequency between 124kHz and 140kHz, supporting up to 28W output power in a flyback topology. Key features include selectable current limiting, extensive built-in fault protection mechanisms such as over-temperature, over-voltage, open-loop, and short-circuit protection, and a maximum duty cycle of 67%. Its isolated output and surface mount capability make it suitable for applications in consumer electronics, industrial automation, and appliance power supplies.
