Question:admin
buck power control IC, as long as the external MOSFET and an output of a diode can be designed to Buck / Boost output, shown in Fig. The working principle of this regulator is that when Lx is high voltage, the inductor current in accordance with the Vin / L increased the slope; Lx is low voltage, the inductor current will be in accordance with (Vout + VD) / L reduced the slope. Intermittent input and output current, which allows the output voltage higher or lower than the input voltage.
