Product details

Boost converter for single-cell battery designs

The TPS61002DGSG4 is a fixed-output step-up (boost) DC-DC converter from Texas Instruments, designed to generate a regulated 1.8V rail from a single-cell alkaline or NiMH battery that can drop as low as 0.8V. It integrates a 1.3A switch and switches at 500kHz, allowing small external inductors and capacitors.

With an input range from 0.8V to 1.8V, this converter works directly from a single alkaline cell (nominal 1.5V) down to its end-of-life voltage, or from a single NiMH cell (nominal 1.2V). The fixed 1.8V output is set internally — no external resistor divider needed, which saves two components and one feedback pin. The 1.3A switch current limits the maximum output current to roughly 700 mA at 1.8V from a 1.2V input, assuming typical efficiency — enough for a sensor node, Bluetooth module, or small microcontroller.

Housed in a 10-VSSOP (also described as 10-TFSOP/MSOP, 3.00mm width) surface-mount package, supplied in Tube.

Frequently asked questions

What is the replacement for TPS61002DGSG4?

No official replacement or successor part number is recorded for the TPS61002DGSG4. For a pin-compatible alternative within the same family, check the TPS6100x series from TI — many share the same pinout and package, but confirm the output voltage and switch current match your design.

Does TPS61002DGSG4 require an external Schottky diode?

Yes, because the TPS61002DGSG4 does not integrate a synchronous rectifier. A Schottky diode from the switch pin to the output is required for the boost topology to function.
