Working Principles

The 72V831L20PF is a voltage regulator IC that converts an input voltage within the range of 6V to 80V into a regulated output voltage between 1.2V and 60V. 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 switching transistor accordingly. The soft-start function gradually ramps up the output voltage to prevent excessive current flow during startup.
