Input current in smps

What would be the input current in smps I/P voltage:24VDC O/P voltage:5V,65W
 

Input current in smps

Hi,
An ideal situation with 100% efficiency would mean an input current of 2.71A. But this is impractical and in real life the efficiency can be between 70% to 90%.
Assuming 90% input current = 3A
At 80%, 3.39A.
At 70%, 3.87A
So, without knowing your efficiency, the best guess could be ~3.5A.
Hope this helps.
Tahmid.

HI dear universally
1. Calculate the o/p capacity (Watt)

2. Assume efficiency which is whole s/m efficiency.

3. Finally calculate the i/p watt of the s/m.

4. you have i/p voltage which is variable for closed loop control. Take min i/p voltage and find max. i/p current flow.
