Power Integrations TOPSwitch®-HX series TOP257GN is an 8-SMD (7 Leads), Gull Wing, surface mount offline PWM controller. This device features an integrated 700V power MOSFET, enabling high-performance flyback converter designs with up to 41W output power. Operating at a 66kHz switching frequency with a 78% duty cycle, the TOP257GN incorporates robust fault protection, including current limiting, over-temperature, and over-voltage protection. Its compact SMD-8C package and isolated output topology make it suitable for a wide range of AC-DC power supply applications, including consumer electronics, industrial controls, and appliance power. The internal switch simplifies design and reduces component count.
