TOP270KG

The Power Integrations TOP270KG is part of the TOPSwitch-JX family, offering integrated off-line switching solutions with EcoSmart technology for highly efficient power supplies. This device is ideal for applications ranging from 10 W to 245 W, providing energy efficiency across the entire load range.

Key features include a 725V rated MOSFET, multi-mode PWM control for maximum efficiency, and selectable operating frequencies of 132 kHz or 66 kHz. It boasts low no-load consumption below 100 mW at 265 VAC and up to 750 mW standby output power. The device incorporates extensive protection features such as auto-restart, output short-circuit protection (SCP), output over-current protection (OCP), output overload protection (OPP), output overvoltage protection (OVP), and accurate thermal shutdown (OTP).

Available in advanced package options like eDIP-12, eSIP-7C, and eSOP-12, the TOP270KG offers design flexibility for various form factors, including ultra-slim designs. The eDIP-12 package supports up to 117W with a metal heat sink, the eSIP-7C up to 177W, and the eSOP-12 up to 66W, all with universal input capabilities. These packages facilitate efficient heat transfer and simplify meeting design derating requirements.

Typical applications include notebook adapters, generic adapters, printers, LCD monitors, set-top boxes, PC/LCD TV standby power, and audio amplifiers. The design flexibility and integrated features contribute to a low system cost.
