Products Detail

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 circuit, fault protection, and other control circuitry onto a 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 for 1 W input at 230 VAC. The device offers high design flexibility with multi-mode PWM control, 132 kHz operation (with 66 kHz option), accurate programmable current limit, line feed-forward for line ripple rejection, frequency jittering to reduce EMI, and integrated soft-start. Extensive protection features include auto-restart for overload, output short-circuit, over-current, overload, and overvoltage protection, as well as thermal shutdown.
