The TPS61031PWPR is a fixed 3.3 V output boost regulator from Texas Instruments, built around a 3.6 A internal switch. That switch current rating sets the practical output current limit for a given input voltage. Switching frequency is fixed at 600 kHz.
ROHS3 compliant, lead-free, no exemption. The tape-and-reel and cut-tape options cover both prototype and volume assembly without a packaging change.
Yes — like any boost regulator, it needs an inductor, input and output capacitors, and feedback resistors (the evidence does not list specific values, but the datasheet application section provides them). The synchronous rectifier eliminates the external Schottky diode that older boost converters require.
