Key Features
- AEC-Q100 automotive qualification ensures reliable operation across the -40°C to 125°C temperature range required by vehicle-grade designs
- Pulse Frequency Modulation control improves light-load efficiency for battery-powered automotive sensors and always-on standby circuits
- Compact 5-pin SOT-23 package with 1.8 V minimum input enables boost conversion directly from a single-cell battery or low-dropout supply rail
Applications
The TPS61041AQDBVRQ1 is designed for automotive infotainment, cluster displays, and always-on sensor nodes that require a step-up from a 1.8 V to 6 V source rail to a higher regulated output voltage. Its AEC-Q100 qualification and PFM control architecture make it particularly suitable for battery-backed RTC and memory supply rails in automotive body electronics where long quiescent operation without load is common. Consumer portable devices and wireless sensor nodes also use this boost converter to extend battery life by maintaining regulated 3.3 V or 5 V output from a single alkaline or Li-ion cell.

Frequently Asked Questions
Which automotive qualification level does TPS61041AQDBVRQ1 carry, and what temperature range does it cover?
The TPS61041AQDBVRQ1 is qualified to AEC-Q100 Grade 1, which covers an ambient operating temperature range of -40°C to 125°C. This grade is appropriate for automotive underhood and dashboard applications where temperature extremes are common, ensuring the boost converter meets automotive reliability and failure-rate requirements for series production vehicles.
How does PFM control in TPS61041AQDBVRQ1 benefit always-on automotive sensor rails at light loads?
In Pulse Frequency Modulation mode, the TPS61041AQDBVRQ1 reduces the switching frequency proportionally with decreasing load current, cutting switching losses dramatically at light loads such as 1 mA to 10 mA drawn by always-on RTC or CAN transceiver circuits. This keeps quiescent efficiency high during vehicle sleep mode, where the 1.8 V to 6 V input battery rail must sustain standby loads for days or weeks without full system wake.
Can TPS61041AQDBVRQ1 boost a single Li-ion cell down to 2.5 V to supply a 3.3 V logic rail?
Yes, the TPS61041AQDBVRQ1 can boost a Li-ion cell that has discharged to as low as 1.8 V all the way to a 3.3 V output, extending usable battery capacity below the nominal 2.8 V to 2.5 V cutoff that PWM regulators typically cannot sustain. This makes it effective in portable medical devices and handheld instruments designed to maintain a 3.3 V system rail through the full depth of discharge of a 250 mAh single-cell battery.
How does the SOT-23 5-pin package of TPS61041AQDBVRQ1 compare in size to 6-pin SOT-23 boost converters?
The TPS61041AQDBVRQ1 in its 5-pin SOT-23 (R-PDSO-G5) package uses a standard 2.9 mm x 1.6 mm footprint with 5 pins, similar in board area to common 6-pin SOT-23 devices at 2.9 mm x 1.6 mm with slightly tighter routing. The 5-pin arrangement simplifies layout for single-inductor boost topologies, as there is no exposed pad or extra ground pin to route, reducing overall component placement effort in space-limited automotive sensor PCBs.
