VOLTAGE DIVIDER CALCULATOR USING RESISTOR

INPUT :

Resistor 1 value: ohms(Ω) kiloohms(kΩ) megaohms(mΩ) ohms(Ω) kiloohms(kΩ) megaohms(mΩ) volts

OUTPUT :

Voltage Output value: volts Formula:

In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin).Voltage division is the result of distributing the input voltage among the components of the divider. A voltage divider referenced to ground is created by connecting two electrical impedances in series. The two-resistor voltage divider is one of the most common and useful circuits used by Hardware design engineers. The primary purpose of this circuit is to scale down the input voltage to a lower value based on the ratio of the two resistors. This calculator helps to determine the output voltage of the divider circuit with given source voltage and the resistor values. Take note that the output voltage in actual circuits might be different, since resistor tolerance and load resistance (where the output voltage is connected) become factors.

To find the Output Voltage: where, R1 = Resistor 1, R2 = Resistor 2, Vin = Voltage Input, Vout = Voltage Output.

In Buck regulators:

Most of the buck boot voltage regulator output voltage will be controlled using adjustable control pin. In the below figure the ADJ pin is connected to the output voltage of the resistor divider circuit. The voltage at ADJ pin will be controlled using resistor-based divider circuit. In buck boost regulator we can find the Vref voltage. Different output voltages can be generated in buck boost regulator using Vref and feedback.
