Working Principle

The working principle of the V375A5H400BG DC DC Converter is based on the Switching Regulator topology. The device utilizes a transistor switch to regulate the output voltage by controlling the duration of a fixed frequency switching waveform. The device is typically controlled by a Pulse Width Modulation (PWM) signal, which adjusts the duty cycle of the signal to change the output voltage. When the PWM signal is high, the transistor switch is on, and the device draws energy from the input. When the PWM signal is low, the transistor switch is off, and the device is in a closed-loop control.

The V375A5H400BG also features a synchronous rectifier, which allows the device to have higher efficiency. The synchronized rectifier operates in accordance with the PWM signal, ensuring that the output voltage remains at the desired level. The device also features an output voltage ripple filter, which helps to reduce the output voltage noise.
