Product details

Boost converter in a SOT-563 — what the 3 A rating means for your rail

The Texas Instruments TPS61023DRLT is a synchronous step-up (boost) regulator delivering up to 3 A from a single-cell input as low as 0.5 V. That 0.5 V minimum input voltage means it keeps running when a lithium-ion or alkaline cell is nearly depleted — a common requirement in portable instruments, wireless sensors, and battery-backed IoT nodes where the designer wants every last milliwatt-hour out of the cell before cutoff.

The 5.5 V output ceiling matches the 5.5 V maximum input rating.

Frequently asked questions

What are the alternatives to TPS61023DRLT?

The LMR33630APCQRNXRQ1 is a buck (step-down) regulator, not a boost — different topology entirely, so not a functional alternative. The LM2750LD-ADJ/NOPB is a charge-pump step-up, but it only delivers 120 mA versus the TPS61023's 3 A, so it serves a much lower power tier. No pin-compatible boost with the same 3 A rating in SOT-563 is listed as a direct second source.
