Hello friends,
I am trying to design a buck converter that will have an input voltage of 50V output at 25V. I applied 50Khz 50% duty cycle PWM signal but I obtained values:
TLP 250 voltage supply and input voltage supply are different voltage sources
Load= 39 ohms
TLP250 voltage =12.4 V
TLP250 current= 1.54 A
Input voltage =20.4V
Input current= 0.11 A
Output voltage rating=8.45
Normally the input current value should be at least: 8.45 / 39=0.22 A
What is the problem my circuit? If you help me, I will be happy
