Tips: DC-DC boost-buck converter applications

DC-DC converters are commonly used in mobile devices such as mobile phones and notebook computers that are mainly powered by batteries. There are often many sub-circuits in this type of electronic equipment, and the required power supply voltage is also different from the power provided by a battery or an external power supply. And when the battery's power decreases, its voltage also drops. The switching-type DC-DC converter can be used with a battery whose voltage has dropped, so that the voltage of the supply circuit can be maintained within a certain range, so there is no need to use multiple batteries to achieve this purpose.

Most DC-DC converters also regulate the output voltage, but there are some exceptions. For example, high-efficiency LED drive circuits are DC-DC converters that regulate the LED current, and there are simple charge pumps. Is to increase the output voltage to double or triple the original.

DC-DC converters can also be used in conjunction with photovoltaic arrays or wind engines. The purpose is to collect the most energy. This type of equipment is called a power optimizer.

Generally used in commercial power supply 50-60Hz transformer, if the power exceeds a few watts, its volume will be very large, and very heavy, and the copper loss of the winding and the eddy current of the iron core will cause energy loss. DC-DC converters will design circuits so that transformers or inductors can work at higher frequencies, so the components are smaller, lighter, and cheaper. Even this kind of components will be used in some occasions where traditional mains frequency transformers were originally used. For example, household electrical equipment often first rectifies the commercial power supply into direct current, uses the technology of a switching power supply to convert it into a high-frequency alternating current of the required voltage, and finally rectifies it to a direct current of the corresponding voltage. The whole circuit is more complicated than traditional systems with transformers and rectifiers, but it is cheaper and more efficient.
