The TPS63002DRCR from Texas Instruments is the adjustable output voltage version of the TPS6300x family of high-efficiency single-inductor buck-boost converters. With four integrated N-channel MOSFET switches, it provides seamless transition between step-down and step-up operation for battery applications where the input voltage can be above, below, or equal to the output. The output voltage is set by an external resistor divider from 1.2V to 5.5V, offering design flexibility. The device delivers up to 1.2A in buck mode and 0.8A in boost mode at 3.3V output, with peak efficiency of 96%. The 2.4MHz switching frequency minimizes external component size, and power-save mode maintains efficiency at light loads.

The TPS63002 uses a 4-switch single-inductor buck-boost topology with average current-mode control. (1) The voltage error amplifier compares the divided-down FB pin voltage against the internal reference, producing an error signal that controls the average inductor current through a fast inner current loop. Input and output voltage feedforward improves transient response. (2) The 4-switch topology automatically selects between buck mode (VIN > VOUT, using S1/S2), boost mode (VIN < VOUT, using S3/S4), or pass-through, always using only two actively switching MOSFETs to maximize efficiency. (3) The power-save mode reduces switching frequency at light loads by skipping pulses, while forced PWM mode via PS/SYNC pin maintains constant frequency for noise-sensitive applications.
