Working Principle

The AVD75B-48S3V3-6L DC DC converter is a high-efficiency non-isolated buck topology DC-DC converter. As a non-isolated buck converter, it takes an input voltage from 48V to 75V and regulates it down to a specified output voltage of 3V to 6V. This is done by a switching transistor which is switched on and off by a control IC. The switching frequency is typically around 100kHz.

When the transistor is on, it forms a closed loop. It connects the input voltage from the power supply to the load. The duty cycle of the switching transistor is controlled by a feedback controller, which adjusts the duty cycle to ensure that the output voltage is maintained constant. This ensures a highly efficient and stable conversion of the input voltage to the output voltage.
