The Power Integrations TOPSwitch®-GX TOP249R-TL is an off-line switcher IC designed for flyback topologies. This device integrates a 700V power MOSFET with a PWM controller, frequency jitter, and comprehensive fault protection including current limiting, over-temperature, and over-voltage protection. Its switching frequency range is 66kHz to 132kHz, with a typical duty cycle of 66.8%. The TOP249R-TL supports up to 79W output power and features internal frequency control. Packaged in a TO-263-7C (D2PAK) surface-mount format, this component is suitable for applications requiring isolated AC-DC conversion, commonly found in consumer electronics, industrial controls, and adapter power supplies. The device operates within a junction temperature range of -40°C to 150°C.
