Working Principles

The TPS61040DRVT operates as a boost converter, which steps up the input voltage to a higher regulated output voltage. It utilizes a switching regulator topology to achieve high efficiency conversion. When enabled, the internal switch (SW) connects the input voltage (VIN) to an inductor, storing energy in its magnetic field. The stored energy is then released to the output capacitor (COUT) when the switch is turned off. This process allows the output voltage (VOUT) to be higher than the input voltage.
