What are the key features of TPS62816-Q1?
- 6 A continuous output current from a 2.7 V to 6 V input with AEC-Q100 automotive qualification for harsh-environment designs
- Ultra-compact 3 mm × 2 mm QFN package with wettable flanks enabling automated optical solder-joint inspection on production lines
- Synchronous buck topology with high switching frequency for small external inductor and capacitor, minimizing solution footprint below 20 mm²
What is TPS62816-Q1 used for?
TPS62816-Q1 is intended for automotive ADAS processors, SoC core supply rails, and in-vehicle infotainment systems that need a regulated output from a 5 V or 3.3 V intermediate bus with up to 6 A load current. Its wettable-flank QFN package simplifies automated AOI inspection in high-volume automotive PCB assembly, supporting the zero-defect quality requirements of TS 16949 production.

Frequently Asked Questions
What input voltage range does TPS62816-Q1 support, and which automotive bus rails does it serve?
TPS62816-Q1 accepts inputs from 2.7 V to 6 V, covering post-regulated 5 V and 3.3 V intermediate bus rails common in automotive domains. This range accommodates both direct-from-5 V ADAS processor power rails and secondary outputs of larger automotive buck converters, enabling 6 A delivery to high-performance SoCs, microprocessors, or FPGA core supply rails inside ECUs.
How do wettable flanks on TPS62816-Q1's QFN package improve automotive production quality?
Wettable flanks expose a thin layer of solderable metal on the side of each QFN lead, creating a visible solder fillet during reflow. This allows automated optical inspection (AOI) systems to confirm solder joint quality without X-ray, reducing inspection cycle time by roughly 30 % in high-volume lines. Automotive suppliers requiring zero-defect soldering per IPC-A-610 Class 3 benefit directly from this feature in small 3 mm × 2 mm packages.
What output current and switching performance does TPS62816-Q1 deliver for ADAS core rail applications?
TPS62816-Q1 delivers up to 6 A continuous output current with a synchronous buck topology, switching at a high frequency that keeps external inductor values below 1 µH. At a 5 V input stepping down to 1.8 V at 6 A, the device achieves efficiency above 90 %, which reduces thermal dissipation inside tightly packed ADAS ECU enclosures and lowers heatsink requirements compared to linear regulators dissipating over 19 W at the same conditions.
Is TPS62816-Q1 AEC-Q100 qualified, and which automotive operating temperature grade does it meet?
Yes, TPS62816-Q1 is AEC-Q100 qualified for automotive use, rated for operation from -40°C to 125°C ambient (Grade 1). This qualification covers high-temperature operating life, temperature cycling, humidity testing, and ESD stress above 2 kV HBM, making the device suitable for under-hood and cockpit-domain ECUs that must pass PPAP documentation and automotive functional safety assessments under ISO 26262.
