Description

TOPSwitch-JX cost effectively incorporates 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.

Product Highlights

EcoSmart – Energy Effcient

• Ideal for applications from 10 W to 245 W

• Energy effcient over entire load range

• No-load consumption below 100 mW at 265 VAC

• Up to 750 mW standby output power for 1 W input at 230 VAC

High Design Flexibility for Low System Cost

• Multi-mode PWM control maximizes effciency at all loads

• 132 kHz operation reduces transformer and power supply size

• 66 kHz option for highest effciency requirements

• Accurate programmable current limit

• Optimized line feed-forward for line ripple rejection

• Frequency jittering reduces EMI flter cost

• Fully integrated soft-start for minimum start-up stress

• 725 V rated MOSFET

• Simplifes meeting design derating requirements

Extensive Protection Features

• Auto-restart limits power delivery to <3 during overload faults

• Output short-circuit protection (SCP)

• Output over-current protection (OCP)

• Output overload protection (OPP)

• Output overvoltage protection (OVP)

• User programmable for hysteretic/latching shutdown

• Simple fast AC reset

• Primary or secondary sensed

• Line undervoltage (UV) detection prevents turn-off glitches

• Line overvoltage (OV) shutdown extends line surge withstand

• Accurate thermal shutdown with large hysteresis (OTP)
