Working Principles

The TPS61043DRBTG4 operates as a step-up (boost) voltage regulator. It utilizes a switching topology to efficiently convert the input voltage to a higher output voltage. The device employs an internal power switch, inductor, and capacitor to perform the voltage conversion process.

When enabled, the TPS61043DRBTG4 controls the power switch to rapidly switch between the input and output sides. This switching action stores energy in the inductor during the "on" state and releases it to the output during the "off" state. By regulating the duty cycle of the switching action, the device adjusts the output voltage according to the feedback received from the FB pin.
