In this installment of Circuit VR, we’ll look at a simple buck converter — that is a switching regulator that takes a higher voltage and produces a lower voltage. The first one won’t ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed ...

All buck converters ... Even so, circuit designers sometimes overlook the maximum RMS current specified in ceramic capacitor datasheets. Therefore, it is important to understand the RMS currents in ...
