Working Principles

The TPS60401DBVR is a step-up voltage regulator that utilizes an internal switch to boost the input voltage to a higher regulated output voltage. It operates by controlling the duty cycle of the internal switch to maintain the desired output voltage.

When the enable pin (EN) is high, the regulator is turned on, and the input voltage (VIN) is boosted to the desired output voltage (VOUT). The feedback pin (FB) is used to adjust the output voltage by providing a reference voltage.

The TPS60401DBVR also incorporates various protection features such as overcurrent and thermal protection to ensure safe operation.
