Working Principles

The TPS63001DRCT operates based on a synchronous buck-boost topology. It uses an internal high-frequency oscillator to control the switching of the internal power MOSFETs. The converter automatically transitions between step-up and step-down modes, depending on the input and output voltage levels.

When the input voltage is higher than the desired output voltage, the TPS63001DRCT operates in step-down mode, regulating the output voltage by adjusting the duty cycle of the internal switches. Conversely, when the input voltage is lower than the desired output voltage, the converter operates in step-up mode, boosting the voltage to the desired level.

The feedback voltage pin (FB) allows for adjustable output voltage through external resistors, providing flexibility in various applications.
