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 features EcoSmart™ – energy-efficient technology, high design flexibility for low system cost, and extensive protection features. Typical applications include notebook or laptop adapters, generic adapters, printers, LCD monitors, set-top boxes, PC or LCD TV standby, and audio amplifiers. It also features output overvoltage protection (OVP), line Undervoltage (UV) detection that prevents turn-off glitches, line overvoltage (OV) shutdown that extends line surge withstand, and accurate thermal shutdown with large hysteresis (OTP).
Features:
- 177W (adapter), 244W (open) at 230VAC and 118W (adapter), 177W (open) at 85-265V O/P power
- Energy efficient over the entire load range, no-load consumption below 100mW at 265VAC
- Up to 750mW standby output power for 1W input at 230VAC
- Multi-mode PWM control maximizes efficiency at all loads
- 132KHz operation reduces transformer and power supply size
- Accurate programmable current limit, optimized line feed-forward for line ripple rejection
- Fully integrated soft-start for minimum start-up stress, frequency jittering reduces EMI filter cost
- 725V rated MOSFET, simplifies meeting design derating requirements
- Output short-circuit protection, output overcurrent protection, output overload protection
- Optimized line feed-forward for line ripple rejection
