Working Principles

The TPS2065CDBVT-2 operates by controlling the flow of current between the input and output pins. When the enable pin (EN) is activated, the internal power switch connects the input voltage (IN) to the output (OUT), allowing power to be supplied to the load. The current limit can be adjusted using the ILIM pin, ensuring that the connected components receive an appropriate amount of current without exceeding their limits.

In case of an overcurrent condition, the integrated overcurrent protection mechanism quickly shuts off the power switch, preventing damage to the load. Additionally, the thermal shutdown feature activates if the IC's temperature exceeds a safe threshold, further safeguarding the device and connected components.
