Models of dc Efficiency as a design objective is what distinguishes a switching power supply from a linear regulator: a linear regulator is designed to process power in one direction, from a large reservoir of power to a small consumer, while in the process wasting a (possibly substantial) fraction of the power drawn from the source to accomplish regulation.Figure 29.24 * Figure 29.22's Efficiency vs Output Current.

Figure 29.25 is another buck type switching regulator, but features a low loss linear post regulator, quiescent current of 40mA and 50mA output.capacity. The LT1020 linear regulator provides lower noise than a straight switching approach. Additionally, it offers internal current limiting and contains an auxiliary comparator which is used to form the switching regulator.lllBiIl' l'B!|ll|fll0l'S l0l' |l0l'tflll|B 3|l|l|l0fltl0lIS Sunnyvale, CA dvances in voltageregulator design are keeping pace with the demands for low cost long battery life, and small size in the design of power supplies for portable electronic products. The result has been a general rewrite of specifications for the latest generation of powersupply ICs. Both switchmode and linear voltage regulators have participated in this transformation. Despite the predominant use of switchmode (or switching) With.a digital load, the linear regulator provides an improvement by the factor p. Regardless of the load type, a switching regulator results in a value of K which is that for a linear regulator, multiplied by an additional factor r)p. vs. Extra. Battery. Size. While DCDC conversion can significantly improve system runtime, this same enhancement of runtime may also be achieved by simply increasing the capacity of the battery source. Thus, from a system design standpoint, it is important to an ideal regulator are that it should have zero sensitivity to changes in Vs (dc input voltage), 1L (output load current) and T, the environment temperature as indicated in the caption of the figure. Regulators are of two types: 1. Linear.regulator. The transistor is always in the active region and conducts continuously. Any change in the output voltage is countered by a shift in the operating point of the transistor so as to modify the current conducted by the transistor. 2. Switching regulator.6.2.8 Linear Regulator versus Switching Regulator The high internal power dissipation and poor efficiency may be acceptable tradeoffs for the good performance of the linear regulator, when the power requirements are small. But at higher power levels, these limitations become almost prohibitive. The choice then always falls on the switching type of regulator. A switch mode power supply uses one or more power semiconductor switching elements, such as a power MOSFET, 3.4 Seriesshunt.feedback for a nonlinear system: switching converter a seriesshunt feedback used for a nonlinear power supply. The major difference between a linear and a nonlinear power supply is whether the input and the output are connected all of the time. In the linear regulator shown in Fig. 3.3, the power MOSFET always connects the power input to its output. In other words, the power MOSFET operates in Class A with 180◦ conduction angle.

The schematic in Figure 51.1 shows to maintain regulation. Figure 51.3, which shows the efficiency of the buck regulator vs load current, also illustrates the typical efficiency gains from using Burst Mode operation at load currents below 100mA.At long last, here is the thoroughly revised.and updated third edition of the hugely successful The Art of Electronics.
