Boost regulator with a 1.3 A switch and 500 kHz switching
The TPS61007DGSG4 is a step-up (boost) DC-DC converter from Texas Instruments, adjustable output from 1.5 V to 3.3 V, with a single integrated switch rated at 1.3 A.
Minimum input of 0.8 V means this part can start from a nearly depleted single-cell alkaline or NiMH battery. Maximum input is 3.3 V, so it is not intended for 5 V or 12 V rails — stay within the 0.8 V to 3.3 V window. The output is adjustable from 1.5 V up to the same 3.3 V ceiling, and the positive output configuration suits single-rail loads.
ROHS3 compliant.
Package and footprint — 10-VSSOP, 3.00 mm width
The 10-VSSOP measures 3.00 mm body width. The exposed pad is on the bottom — ensure the PCB thermal land connects to a ground plane pour for heat spreading. No synchronous rectifier means the external Schottky diode carries the output current; pick a diode rated for at least the 1.3 A switch current and the output voltage.
