TOP264EG [Power Integrations]

The TOP264-271 is part of the TOPSwitch-JX Family, integrating a 725 V power MOSFET, high-voltage switched current source, multi-mode PWM control, oscillator, thermal shutdown, and fault protection into a single monolithic device. It features EcoSmart energy efficiency with no-load consumption below 100 mW at 265 VAC and up to 750 mW standby output power at 230 VAC. The device offers high design flexibility with multi-mode PWM operation (132 kHz/66 kHz), programmable current limit, frequency jittering for EMI reduction, and integrated soft-start. Extensive protection includes auto-restart, output short-circuit/over-current/overload/overvoltage protection, hysteretic/latching shutdown, line UV/OV detection, and thermal shutdown. Available in eDIP-12, eSIP-7C, and eSOP-12 packages with thermal management options.
