How To Make High Power DC-DC Booster Circuit | Buck-Boost Converter

Step 1: Solder inductor, diode, capacitor, MOSFET, and resistor on PCB dot board as per the circuit diagram fig1. Step 2: Set the power supply voltage to 5V or take a 5V phone adapter. Step 3: Solder the positive side (A) of the power supply to the Inductor leg and the negative side of the power supply to the ground (G).

It requires only a few external components. The IC consists of many good features and functions system. Built inside its circuitry are, a built-in 3A NPN switch at the output, 52 kHz oscillator, current limit function, automatic overheat shutdown, automatic over-voltage shutdown, etc.

A boost converter or step-up converter aids in stepping up a DC voltage from the input to the output line. The conduction state of the switch dictates the operation of the circuit diagram. During the on-state, the electrical current flowing through the inductor increases linearly.

The output DC voltage is increased by adding capacitors to the full-wave and half-wave rectifier system. The voltage multiplier circuit is made by connecting a capacitor and a diode (ex: 1N4007w). In many circuits where the output Line voltage must be greater than the input voltage, capacitors can be used.

Power brake boosters use a vacuum from the engine, or a standalone Motor pump, to assist in slowing down the vehicle as you depress the brakes. This makes the brake pedal much easier to press down and improves the braking response of the vehicle system.
