Working Principles

The TPS2065DBVT operates by monitoring the input voltage and controlling the power switch accordingly. When the enable pin (EN) is activated, the IC allows current flow from the input (IN) to the output (OUT). It continuously monitors the output voltage through the feedback pin (FB) and protects against overcurrent conditions. In case of excessive temperature, the thermal shutdown feature activates, temporarily disabling the power switch until the temperature returns to a safe level.
