Power Integrations TOPSwitch-HX电源解决方案
TOP254-258 TOPSwitch-HX Family
TOPSwitch-HX cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.
产品亮点:
Lower System Cost, Higher Design Flexibility
Multi-mode operation maximizes effi ciency at all loads
No heatsink required up to 35 W using P, G and M packageswith universal input voltage and up to 48 W at 230 VAC
Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset
Allows both primary and secondary sensing
Line undervoltage (UV) detection prevents turn-off glitches
Line overvoltage (OV) shutdown extends line surge limit
Accurate programmable current limit
Optimized line feed-forward for line ripple rejection..
