WebJun 8, 2024 · This is because a switching regulator is very efficient, as shown in the table below. The three common topologies for switching regulators are buck (step-down), boost (step-up), or buck-boost (configurable by adjusting the duty cycle of a PWM signal). As mentioned above, the final regulator stage could be a linear regulator or LDO regulator. WebUnlike switching voltage regulators, low quiescent current regulators (LDO) cannot be used with buck or boost converters. Buck and boost converters enable the regulator to “step down” or “step up” the voltage respectively. These cannot work with linear voltage regulators, as the input voltage must always remain greater than the output ...
