WebThe load can handle between 10 V and 14 V, but the voltage source has a possible output range of 8 V to 16 V. An interposed buck-boost regulator can thus convert the voltage to 12 V at the output. If the supply voltage is somewhat lower than 12 V, the converter works in boost mode, and if it is above 12 V, it works in buck mode. Webneeds 12 volts, then the power converter works in buck mode. Maximum current flowing through the inductor during this stage is calculated by the equation (4): IL max = Vout 1 Rload + 1-Dbuck 2×f ...

WebAug 31, 2024 · Let's say you have a buck converter capable of operating in both modes of operation. You will find that if it's operating in DCM, the load current has to be low. As the load current rises you reach a point (it's called the boundary point) where the converter is operating on-the-cusp of CCM. Above this point it fully operates in CCM. WebSep 10, 2007 · Buck Converter A buck converter, as its name implies, can only produce lower average output voltage than the input voltage.
