Working Principles

TOP267VGAU is a switching regulator IC that utilizes a flyback topology to convert high input voltage to a regulated low output voltage. It operates by switching the input voltage on and off at a high frequency, which is then transformed and rectified to provide a stable DC output. The feedback mechanism continuously monitors the output voltage and adjusts the duty cycle of the switching transistor to maintain the desired voltage level.
