48 V DC to 5 V DC Converter circuit

  High voltage DC conversion to a low level is tough task , but it is not that difficult task so  this circuit is consist of Transistor based DC voltage  down converter circuit , here a power full transistor TIP35C were used , a smal network of resistor 4.7k , 100R 5W , Zener diode 12V, capacitor 220uf were used , Zener Diode first limited the voltages up to 12 from the input with help of TIP35C , a diode IN4001 used for protection to the circuit, this 12V were then applied to any other regulator IC like 7805 or 7809. any other other powerfull transistor be used like 2SC5200.
