Working Principles

The TPS61041DRVTG4 is a boost converter that utilizes a switching regulator topology. It operates by rapidly switching an internal power switch to control the energy transfer from the input to the output. This switching action allows for efficient voltage conversion with minimal power loss.

When the input voltage is applied, the internal switch alternates between connecting the input voltage to an inductor and disconnecting it. This action causes the inductor to store energy during the "on" state and release it to the output during the "off" state. By controlling the duty cycle of the switch, the output voltage can be regulated to the desired level.
