WebFigure 2: Efficiency Chart of the MPQ4572 Buck Converter with the MPL-AL6060-150 15µH Inductor. Figure 3 shows an efficiency breakdown of a 24V to 5V buck converter with a 2A load. While the inductor and MOSFETs have 870mW of power loss, quiescent power consumption adds just 900µW to the total sum. WebA buck converter steps down the input voltage (V_IN) to a lower-level output voltage (V_OUT), and the main equation characterizing its behavior is given by: Equation 1 A 48V/12V DC/DC step-down buck converter shown in Fig. 1 is usedas the example in this paper. A buck converter steps down the inputvoltage(V_IN)toa lower-level output voltage
A buck converter or step-down converter is a DC-to-DC converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). It is a class of switched-mode power supply. Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC … See more The basic operation of the buck converter has the current in an inductor controlled by two switches (fig. 2). In a physical implementation, these switches are realized by a transistor and a diode, or two transistors (which … See more There are two main phenomena impacting the efficiency: conduction losses and switching losses.
