What are the key features of TPS629210QDRLRQ1?
- AEC-Q100 qualified automotive-grade device supporting -40°C to +125°C operation
- Dual PWM/PFM control modes enabling efficiency above 90% from light to heavy loads
- Wide 3 V to 17 V input voltage range in a compact 8-pin SOT flat-lead package
What is TPS629210QDRLRQ1 used for?
TPS629210QDRLRQ1 is designed for automotive infotainment, ADAS sensor rails, and cluster power supplies where AEC-Q100 reliability is mandatory. Its 3 V to 17 V input range accommodates direct connection to 12 V vehicle battery rails after transient protection, delivering regulated outputs for microcontrollers and sensors. The PFM mode reduces quiescent current during idle states, extending battery life in stop-start and always-on automotive subsystems.

Frequently Asked Questions
Which automotive system rails can TPS629210QDRLRQ1 regulate directly from a 12 V car battery?
TPS629210QDRLRQ1 accepts inputs from 3 V to 17 V, covering the full 12 V automotive battery range including cold-crank dips to approximately 6 V. It can supply regulated 3.3 V or 5 V outputs at continuous load currents, making it suitable for ADAS sensors, gateway ECUs, and instrument cluster microcontrollers without a pre-regulator stage.
How does PFM mode in TPS629210QDRLRQ1 reduce power consumption at light loads?
In PFM mode, TPS629210QDRLRQ1 skips switching pulses when output current falls below a threshold of approximately a few milliamps, reducing switching losses and quiescent current to under 30 µA. This yields efficiency improvements of 10% to 20% compared to fixed-frequency PWM at loads below 10 mA, which is critical for always-on automotive circuits during vehicle park mode.
What does the AEC-Q100 qualification mean for TPS629210QDRLRQ1 in a production automotive design?
AEC-Q100 qualification confirms TPS629210QDRLRQ1 has passed automotive stress tests including thermal cycling from -40°C to +125°C, electromigration, and ESD per HBM 2 kV. This qualification is mandatory for Tier-1 automotive supplier BOMs and simplifies PPAP documentation, reducing design-in risk and ensuring supply chain traceability across a 15-year product lifecycle.
