P LOSS = V OUT I S + ( I OUT + I S ) R S. INTRODUCTION. However, if we control the output voltage VOUT by The industry drive toward smaller, lighter and more varying RS and keeping IS zero, the ideal Power loss efficient electronics has led to the development of the inside the converter can be calculated as shown in Switch Mode Power Supply (SMPS). There are several Equation 2. Topologies commonly used to implement SMPS. This application note, which is the first of a two-part EQUATION 2: SERIES-CONTROLLED. series, explains the basics of different SMPS.
Sep 10, 2007 · waveforms of a buck converter is shown in Figure 2. In a buck converter, a switch (Q1) is placed in series with the input voltage source V IN. The input source VIN feeds the output through the switch and a low-pass filter, implemented with an inductor and a capacitor. In a steady state of operation, when the switch is ON for
