TOP264EG

The Power Integrations TOP264EG is part of the TOPSwitch-JX family, an integrated off-line switcher with EcoSmart™ Technology. This device is designed for highly efficient power supplies, ideal for applications ranging from 10 W to 245 W. It features a 725V rated MOSFET and multi-mode PWM control that maximizes efficiency across the entire load range.

Key design features include a 132 kHz operation for reduced transformer and power supply size, with an optional 66 kHz for highest efficiency requirements. It offers accurate programmable current limit, optimized line feed-forward for ripple rejection, and frequency jittering to reduce EMI filter costs. The device includes fully integrated soft-start for minimum start-up stress and simplifies meeting design derating requirements.

Extensive protection features are built-in, including auto-restart for overload faults, output short-circuit protection (SCP), output over-current protection (OCP), output overload protection (OPP), and output overvoltage protection (OVP). It also provides line undervoltage (UV) detection and accurate thermal shutdown with hysteresis (OTP).

The TOP264EG is available in an eSIP-7C package, which is a vertical orientation for minimum PCB footprint. It supports simple heat sink mounting using a clip, providing thermal impedance equivalent to a TO-220. The mounting type is Through Hole.
