When Grounds are Separated

Click image to enlarge

How should you proceed with a switching regulator with an analog ground (AGND) and a power ground (PGND)? This is a question asked by many developers designing a switching power supply. Some developers are accustomed to dealing with a digital GND and an analog GND; however, their experience frequently fails th

Figure 1. Boost topology for generating a high voltage from a low voltage

If a high voltage needs to be generated from a low voltage, a boost converter can be used. This represents one of the three elementary switching regulator topologies and requires only two switches, an inductor, and input and output capacitors. Besides the boost converter, the other basic topologies are the buck co
