Working Principles

The 72V825L20PF is a voltage regulator IC designed to regulate and protect high voltage power supplies. It operates by continuously monitoring the input voltage and adjusting the output voltage accordingly. The feedback pin (FB) allows users to set the desired output voltage, which can be adjusted within a wide range.

The IC incorporates various protection features such as overvoltage, undervoltage, and overcurrent protection. These safeguards ensure that the output voltage remains within safe limits and prevent damage to connected devices.

Additionally, the soft-start feature gradually ramps up the output voltage during startup, preventing excessive inrush current that could potentially damage the IC or other components.
