Tips: Different types of DC-DC converter

• Non-isolated DC-DC converter
  Non-isolated DC-DC converters have direct connections between input and output circuits. Compared to isolated models, they are used for low-power equipment to benefit from their relatively lower cost, smaller size, and higher efficiency, as no transformer will lose energy. This type is used in communications, computers, automobiles, and other industries.
• Isolated DC-DC converter
  In isolated converters, input and output are separated from each other. It prevents dc current between two circuits. Usually, the primary and secondary circuits are kept separate for safety reasons, which is why this design is widely used for high-voltage DC-DC converters. In addition, isolated DC-DC converter allows you to disconnect ground loops to protect sensitive circuits from noise.
• Buck DC-DC converter
  Also known as step-down converters and choppers, they produce a lower output voltage than the input. In a simple buck converter, the switching element quickly turns power on and off. The output voltage looks like a series of square waves. When the switch is turned on, the coils and capacitors accumulate energy. The capacitor also smoothes these waves into a DC voltage. When the voltage reaches the required level, the switching element closes and the diode turns on. Self-induced electromotive force causes a current to flow through the diode. The accumulated energy in the coil charges the load.
• Boost DC-DC converter
  Also known as DC-DC step-up converters, they can produce a voltage higher than the input voltage. In a typical boost converter, the induction coil receives almost all the current, and the closing diode does not allow the current to charge the capacitor and load. Due to the higher current, the coil will accumulate more magnetic field energy than the step-down schematic. When the voltage drops to a certain point, the power button turns off and the diode turns on. The input voltage increases the energy stored in the coil, which makes the output voltage of the boost DC-DC converter higher than the input voltage.
