This application note explains the calculation of external capacitor value for buck converter IC circuit. Change of capacitance value due to temperature can obtain stable temperature characteristic by ...

To see a video on this topic by the author, click here. Figure 1 provides a plot of this expression; it is a circle with a maximum of 0.5, at 50% duty factor and two zero crossings at zero and 100% ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

In the conventional dc-dc converter buck topology (Fig. 1), power from the input voltage source is transferred to the output filter by turning on the pass transistor. When the pass transistor is on, ...
