Product Details
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 Efficient
- Energy efficient over entire load range
- No-load consumption below 70 mW at 230 VAC achievable
- 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 efficiency at all loads
- 132 kHz operation reduces transformer and power supply size
- 66 kHz option for highest efficiency requirements
- Accurate programmable current limit
- Optimized line feed-forward for line ripple rejection
- Frequency jittering reduces EMI filter cost
- Fully integrated soft-start for minimum startup stress
- 725 V rated MOSFET
- Simplifies meeting design derating requirements
Extensive Protection Features
- Auto-restart limits power delivery to <3% during overload faults
- Output short-circuit protection (SCP)
- Output overcurrent 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)
