In the design of power supplies; the desired output voltages can be set manually. This is accomplished in most integrated power supply circuits; as well as switching and linear regulator ICs; with the help of voltage dividers. The ratio of the two resistance values must be suitable to enable the desired output voltage to be set. Figure 1 shows a voltage divider. The internal reference voltage (VREF) and the desired output voltage determine the ratio of the resistance values; as seen in Equation 1: [Formula presented] © 2024 Findlay Publications Ltd.
