请问 这款电源用什么方案做,用什么IC,请看下面 SPEC !!!

1. Input
1.1 Input voltage: 100-240VAC Type, Max operates range at 85- 264Vac.
1.2 Frequency Range 50-60Hz Type  
1.3 Primary current: 0.3A max
1.4 Idle state input power 0.5W max
1.5 Inrush current <37A @264 V AC input.

2. Output
2.1 Output Voltage: 5V & 24.0V
2.2 Output Loading: 0-1A @ 5V, 0-0.2A @ 24V
2.3 Tolerance: +/-5% @ 5V & 24V
2.4 Ripple & Noise (Vp-p): < 1% of rated output voltage.
Note: The measurement for differential ripple and noise the output will be using oscilloscope, with 20MHz bandwidth. A 10uF electrolytic capacitor and a 0.1uF ceramic capacitor should be parallel with output load.

3. General characteristics
3.1 Efficiency: >82% @ AC100-240V full load.
3.2 Protection function:
3.2.1 Output short circuit protection auto-recovery
3.2.2 Output over voltage protection 6.8V max @ 5V output and 32V max @ 24V output (auto recovery)
3.2.3 Over temperature protection 88-100℃ Component temperature
auto-recovery
3.2.4 Output over current protection 1.1-1.3A at 5V output and 0.25-0.35A at 24V output auto-recovery during input AC100-240V, Output full load estate.
3.2.5 Input under voltage lockout (UVLO) Under 40-- 60 V AC

4. Hi-pot
4.1 Input to output 3000 V AC 50Hz for leakage 5mA at 1 minute.
4.2 Input to case 3000 V AC 50Hz for leakage 5mA at 1 minute.

普通的反激就行了呗,FSD210就可以办了,SPEC方案好像只能用在非隔离电路上
