WebFeb 18, 2016 · A buck converter steps a voltage down, producing a voltage lower than the input voltage. A buck converter could be used to charge a lithium ion battery to 4.2 V, from a 5 V USB source. Figure 1: Buck converter A boost converter steps a voltage up, producing a voltage higher than the input voltage. WebDC converters rapidly switch on and off as necessary to reach the desired output voltage whereas a linear regulator just looses all power over whatever the voltage drop is. So if you step down 9V to 2.5V and the devices draws 100mA that's 9-2.5*0.1*6.5=4.2W. But if you drop 3.3V to 2.5V and it draws 5mA that's only 3mW. WebNov 12, 2024 · What is a Buck Converter?
