The Power Integrations TOPSwitch®-GX series TOP246Y is an offline flyback converter IC designed for high-efficiency power supply applications. This component features integrated 700V switching capability and operates within a switching frequency range of 66kHz to 132kHz. Key control features include on-chip frequency control and a maximum duty cycle of 66.5%. The TOP246Y offers robust fault protection with built-in current limiting, over-temperature, and over-voltage protection mechanisms. Packaged in a TO-220-7C, this device is suitable for through-hole mounting and supports isolated output topologies. Its high power output capability of up to 125W makes it ideal for use in consumer electronics, industrial control systems, and power adapters. The operating temperature range is -40°C to 150°C (TJ).
