Working Principles

The BD8105FV-E2 is a voltage regulator IC that converts an input voltage within the range of 4.5V to 18V into a regulated output voltage between 0.8V and 16V. It utilizes a switching regulator topology to achieve high efficiency and low power consumption. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the internal switch to maintain a stable output. The compensation pin (COMP) allows for fine-tuning of the control loop stability.
