MT3608 DC-DC Converter: Datasheet, Circuit, Schematic
A boost converter (DC-DC step-up converter) is used to step up a lower voltage to a higher voltage level with quite a simple circuitry. It is a type of switch-mode power supply as it uses a switching device to regulate the voltage. In our case, the switching module is the MT3608 IC which has a high switching frequency of 1.2MHz.
