AIH20B300-L

DC-DC converters are used to provide a voltage or current source for a given load or system. The primary purpose of a DC-DC converter is to convert a DC voltage source of a given magnitude into an adjustable output voltage or current of a higher or lower magnitude. For example, a 12V DC-DC converter can convert a 12V DC source into an adjustable output voltage or current of a higher or lower magnitude, such as a 24V or 6V DC source.

The working principle of the AIH20B300-L converter module is based on the buck converter topology. The buck converter is a type of DC-DC converter that operates by using a switching transistor to switch the inductor current with the output load. The working of a buck converter can be explained in the following sequence:

1. When the switching transistor is on, the input voltage is applied to the inductor and the inductor currents starts to increase. The output voltage is equal to zero at this time.

2. When the switching transistor is off, the inductor current continues to flow due to the magnetic field stored in the inductor and the output voltage is equal to the input voltage.

3. The output voltage can be controlled by adjusting the switching frequency of the switching transistor, as well as the inductance of the inductor.

4. The energy stored in the inductor is then transferred to the load through the diode.

The working of the AIH20B300-L DC-DC converter is similar to that of a typical buck converter. In addition, the AIH20B300-L has an internal current sensing circuit to provide a precise output current limit range of 0.1-22A, as well as an internal temperature sensing circuit to provide over-temperature protection.
