Working Principles

The TPS61041DBVRG4 operates as a boost converter by utilizing an internal switch to control the energy transfer from the input to the output. When the switch is closed, energy is stored in an inductor. When the switch opens, the stored energy is transferred to the output through a diode. This process allows the output voltage to be higher than the input voltage.
