Working Principles

PL685-28DC is a voltage regulator that converts an input DC voltage into a regulated output voltage. It utilizes a control loop to maintain the desired output voltage by adjusting the duty cycle of an internal switching transistor. The feedback pin (FB) monitors the output voltage and provides feedback to the control circuitry, which adjusts the duty cycle accordingly.
