TOP245PN,Integrated Off-line Switcher,DIP-8

The TOP245PN - DIP-8 is a high-efficiency, off-line switcher IC from Power Integrations, part of the TOPSwitch-GX family. It integrates a 700V power MOSFET, oscillator, and control circuitry, offering a cost-effective solution for a wide range of power supply designs. Its universal input voltage range (85V to 265V AC) allows for global usage, making it ideal for applications such as adapters, chargers, industrial power supplies, and appliance control systems.

The TOP245PN supports up to 57W of output power in open-frame designs and up to 33W in enclosed adapter designs when powered by 230VAC. With built-in overvoltage protection, thermal shutdown, and programmable current limiting, the IC ensures safe operation under various load and environmental conditions. The device operates at a 132kHz switching frequency, reducing the size of external components, and includes frequency jittering to minimize EMI, which further simplifies compliance with regulatory standards.

Packaged in a compact DIP-8 form, the TOP245PN is easy to integrate into traditional through-hole designs. Its combination of high-voltage operation, fast switching speeds, and integrated protection features makes it a versatile solution for powering high-efficiency systems in consumer electronics, industrial applications, and low-power devices.
