Step down DC to DC converter

[au.umair]

Dear all,

I have a computer power supply of 300W but it it faulty. I opened the power supply and found that its AC to DC converting unit is still working. The output voltage of this unit is 118Vdc. Now I need to step down this voltage to 24DC 2A. Any suggestions please?

regards

Satau

Dear Satau
Hi
if isolation is not important to you you can use from buck regulator .
but i suggest you Continuous Fly back or In better choice , Forward converter . for forward or fly back you can use UC3844 or Uc3845 IC.
Best lucks
