Description

General part information

TOP268 Series

TOPSwitch™-JX cost effectively incorporates a 725V 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 feature EcoSmart™ – energy efficient technology, high design flexibility for low system cost and extensive protection features. Typical applications includes notebook or laptop adapter, generic adapter, printer, LCD monitor, set-top box, PC or LCD TV standby, audio amplifier. It also features output overvoltage protection (OVP), line undervoltage (UV) detection prevents turn-off glitches, line overvoltage (OV) shutdown extends line surge withstand and accurate thermal shutdown with large hysteresis (OTP).
