Last-time-buy status — plan your final order
For a current automotive boost regulator design, this is the signal to secure your lifetime buy quantity or begin qualification of a replacement.
Automotive-grade boost regulator — 1.8V to 28V envelope
It accepts an input supply from 1.8V to 6V and delivers a regulated output up to 28V, with an internal switch rated for 400 mA per channel.
SOT-23-5 package — footprint and rework
The TPS61040AQDBVRQ1 comes in a SOT-23-5 package. Five pins, surface-mount, with a small footprint that fits into compact automotive PCBs.
This covers automotive under-hood and engine-bay environments, as well as industrial applications where the ambient temperature can push past 85°C. The 125°C ceiling is the junction temperature limit for the internal switch — derate the 400 mA output current above 85°C ambient per the datasheet thermal curves.
Sourcing reality — Last Buy channel
We source it through independent and surplus channels against an RFQ. If you need a production-volume commitment, this is the time to place the order — once the last-time-buy window closes, the surplus channel is the only option.
