Working Principles

The TPS60400DBVT is a step-up voltage regulator that utilizes a boost converter topology. It converts a lower input voltage to a higher output voltage using an internal switch and control circuitry. The feedback pin (FB) is used to regulate the output voltage by providing feedback to the control circuit.

When enabled, the TPS60400DBVT starts switching the internal switch at a high frequency. This allows energy to be transferred from the input to the output through an inductor and capacitor arrangement. The control circuitry adjusts the duty cycle of the internal switch to maintain the desired output voltage.
