Part Number: PMP9202

Hi,

I am designing AC to DC SMPS in automation Field. My Power Supply is requirement in below details-

  1. Input Voltage - (85 to 264) VAC 
  2. Output Voltage- 5VDC/1A or 5VDC/2A (Both are given)
  3. Voltage Accuracy- 1% to 2%
  4. Power -5W/10W
  5. Line and Load Regulation- 2%
  6. Ripple- 50 to 150mV
  7. Efficiency-80 to 90%
  8. Isolation- 4000VAC (Input to Output)
  9. Protection- Over Current, Short Circuit, Over voltage and Temperature Protection.

I have searched some solution. I have some query as per below Reference Design-

Reference Design Number- PMP9202 (85-265) VAC

This Circuit is not used optocoupler 

What is difference this circuit and using Feedback Circuit
