The Power Integrations TOP271EG is part of the TOPSwitch-JX family, an integrated off-line switcher with EcoSmart™ Technology for highly efficient power supplies. This device incorporates a 725V power MOSFET, multi-mode PWM control, oscillator, thermal shutdown circuit, and fault protection onto a monolithic device.
Key electrical specifications include a maximum output power of 244W, selectable operating frequencies of 66kHz or 132kHz, and a 725V rated MOSFET. It features extensive protection mechanisms such as output short-circuit, over-current, overload, overvoltage protection, and accurate thermal shutdown. The device also includes auto-restart functionality that limits power delivery to less than 3% during overload faults.
Designed for high design flexibility and low system cost, the TOP271EG offers features like optimized line feed-forward for ripple rejection and frequency jittering to reduce EMI filter costs. It supports both primary and secondary sensing and includes undervoltage and overvoltage detection for enhanced line surge withstand.
The TOP271EG is available in an eSIP-7C package, which is a 7-pin, single in-line package with formed leads and an exposed pad. This package is suitable for through-hole mounting and offers vertical orientation for minimum PCB footprint. The eSIP-7C package provides a 177W universal input output power capability.
