DC to DC Converter 12 Volt to 21 Volt

Below is a schematic diagram of a DC to DC Converter 12 Volt to 21 Volt by using IC TDA2003.

21V from 12 V DC to DC Converter

This 12 V to 21 V DC to DC Converter can perform nicely at 500mA maximum current. In case the current exceeds 500 milli-amperes, the voltage will drop below 21 Volt.

TDA 2003Part list :

  • R1 : 2M2
  • R2 : 300K
  • C1 : 0,47uF
  • C2 : 47nF
  • C3 : 1000uF electrolityc capacitor
  • C4 : 1000uF electrolityc capacitor
  • D1 & D2 :
  • SB 550
  • IC : TDA2003

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
