You can reconfigure a buck regulator into a buck-boost circuit to convert a positive voltage into a negative voltage (Figure 2). The basic component configurations of both circuits are similar, and the inductor and the rectifier diode are transposed. Because the main switch, Q1, remains in the...
A buck-boost regulator for converting an input voltage to an output voltage which includes an inductor, an error circuit providing an error voltage, buck and boost switching circuits, buck and boost ripple circuits, and buck and boost hysteretic comparator circuits. The buck switching circuit switch...
4.2Circuit Diagram Basic Working principle The basic working principle of a buck-boost converter can be understood with the help of the following explanation. Referring to the basic buck-boost topology diagram above, when the switch S is closed, the input voltage VIN is blocked by the diode D...
boost regulator depends on its mode of operation. When the input voltage is lower than the output voltage, the efficiency of the regulator is that of a boost regulator. When the input voltage exceeds the output voltage, the circuit operates as a linear regulator in which efficiency is ...
