WebAlthough the link to the item is no longer working, in general most available DC-DC buck converter modules have a current limiting function based on a resistor on the output ground to measure current. This will not work if input and output ground are connected together outside the module. The difference between the input and output ground is at ... 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. A … See more If you keep the following basic ideas in mind, you’ll have a good feeling for what will and will not cause ground bounce. Figure 12 shows that … See more
