TOP244YN General Description

The TOP244YN is an integrated off-line switcher with advanced feature set suitable for a wide range of applications. It is a member of Power Integrations’ TOPSwitch-HX family, which combines a high-voltage power MOSFET switch with a power supply control circuit into a single chip. The TOP244YN offers a wide input voltage range of 85 VAC to 265 VAC, making it suitable for use in a variety of mains-powered equipment. It has a maximum output power rating of 41 W, making it ideal for applications such as low-power AC/DC power supplies, LED lighting drivers, and other similar applications.Key features of the TOP244YN include a low standby power consumption of less than 30 mW, which helps to improve energy efficiency. It also features a built-in frequency jittering function that helps to reduce EMI emissions, ensuring compliance with global regulatory standards.The TOP244YN is available in a compact 8-pin DIP package, making it easy to integrate into existing designs. It also features comprehensive protection features, including over-temperature protection, over-voltage protection, over-current protection, and output short-circuit protection, ensuring reliable and safe operation.
