Power Integrations TOPSwitch®-HX series TOP257LG is an offline switcher IC designed for flyback topologies. This component integrates a high-voltage power MOSFET with a PWM controller, oscillator, and protection features into a single eSIP-7F package. It offers selectable switching frequencies of 66kHz and 132kHz, enabling optimization for efficiency and component size. The device provides robust fault protection including current limiting, over-temperature, and over-voltage shutdown. With a breakdown voltage of 700V and a maximum output power of 105W, the TOP257LG is suitable for various AC-DC power supply applications in consumer electronics, industrial control, and lighting sectors. The through-hole mounting and isolated output ensure straightforward integration into existing designs. Operating temperature range is -40°C to 150°C (TJ).
