Among available … For the purpose of discussion, the simple circuit in Figure 3 is similar to—and can be morphed into—the buckconverter in Figure 4. At high frequencies, a large capacitor—such as the buck input capacitor, CVIN—looks like a dc voltage source. Similarly, the large output buck inductor, LBUCK, looks like a dc … See more A boost converter is essentially a reflection of a buck converter, so—as seen in Figure 11—it is the outputcapacitor that must be placed between the top of the high-side switch and the bottom of the low-side switch to minimize … See more Ground-bounce voltage is induced principally by a change in magnetic flux. In a dc-to-dc switching power supply, the flux changes because high speed switches direct current … See more Ground bounce is always a potential problem. For a monitor or TV, it can mean a noisy picture—for an audio device, background noise. In a digital system, it can lead to computation errors—even a system crash.
