Product details

Fixed 5V rail from a variable input

The TPS63002DRCTG4 is a synchronous buck-boost regulator from Texas Instruments that delivers a fixed 5V output from an input voltage that can range from 1.8V up to 5.5V. This means the part can regulate a clean 5V rail whether the input is a 3.3V system bus, a single-cell Li-ion battery dropping to 3.0V, or a 5V USB supply with tolerance — the topology handles the crossover without a mode-change glitch.

1.6A switch current — sizing the load

In a typical 5V-out application from a 3.3V input, expect around 1A continuous output before the switch current limit engages.

The 10-VSON package with exposed pad (3x3 mm) requires a thermal land pattern on the PCB — the datasheet layout recommendation is the starting point for the copper footprint.

Frequently asked questions

Can TPS63002DRCTG4 replace TPS63002DRCR?

The TPS63002DRCTG4 and TPS63002DRCR share the same base product number TPS63002 and the same 10-VSON package. The suffix difference (G4 vs R) typically indicates a lead-free / RoHS compliance variant. Electrical characteristics are identical — the G4 suffix is the greener finish. Pin-compatible, same footprint.
