From the shop's description

TOP245YN Offline AC-DC Power Conversion 5.85v 1.5mA IC TO-220-7C The TOP245YN is a highly integrated offline switch-mode power supply (SMPS) IC designed to simplify the design of AC-DC converters. It combines a high-voltage power MOSFET, PWM controller, oscillator, and protection circuitry into a single compact package, making it ideal for efficient and reliable power supply designs. This integration significantly reduces external component count and overall system complexity. This IC operates using flyback topology and is widely used in low to medium power applications requiring stable and efficient DC output from AC mains. With built-in protection features such as thermal shutdown, current limiting, and auto-restart, the TOP245YN ensures safe and robust operation under various load and fault conditions. It is well-suited for compact, cost-effective designs in consumer electronics and industrial applications. Features: Integrated high-voltage power MOSFET. Built-in PWM controller.
