Key Features
- AEC-Q100 qualified automotive buck converter with 3 V to 17 V input range and 0.6 A output, rated -40°C to 150°C for harsh automotive environments
- Low-IQ synchronous PWM architecture minimizes battery drain in always-on automotive ECU standby modes
- Ultra-compact 8-pin SOT-583 package enables minimal-footprint power supply design in space-constrained automotive modules
Applications
The TPS629206QDRLRQ1 is designed for always-on automotive subsystems such as telematics, gateway ECUs, and body-control modules where low standby quiescent current is critical to extend battery life during ignition-off states. Its 3 V to 17 V input range covers the full automotive 12 V battery voltage window including cold-crank conditions as low as 3 V and load-dump transients up to 17 V. The -40°C to 150°C temperature rating ensures reliable operation in underhood and behind-dashboard mounting locations throughout the vehicle's service lifetime.

Frequently Asked Questions
What input voltage range does the TPS629206QDRLRQ1 support, and can it survive automotive load-dump events?
The TPS629206QDRLRQ1 accepts input voltages from 3 V to 17 V, covering the automotive 12 V nominal rail while tolerating cold-crank drops down to 3 V and standard 17 V load-dump transients defined in automotive specifications. This 14 V input window eliminates the need for external transient voltage suppressors in many 12 V automotive ECU designs, simplifying the power-entry BOM.
How does the low-IQ feature of the TPS629206QDRLRQ1 benefit always-on automotive systems?
The TPS629206QDRLRQ1's low quiescent current operation significantly reduces battery drain when the vehicle is parked and the ECU is in standby mode, which is critical for telematics units, keyless-entry modules, and anti-theft controllers that must remain powered for days or weeks on a 12 V lead-acid battery with no alternator recharge. Lower IQ directly translates to extended parking time before a dead-battery event in these always-on applications.
What is the maximum output current of the TPS629206QDRLRQ1 and what loads can it drive?
The TPS629206QDRLRQ1 delivers up to 0.6 A continuous output current, sufficient to power low-power microcontrollers, wireless communication modules such as Bluetooth or CAN transceivers, and small sensor clusters in automotive body-electronics. At 3.3 V output from a 12 V input, it can supply up to approximately 1.98 W of regulated power with synchronous rectification for high conversion efficiency.
What temperature range does the TPS629206QDRLRQ1 support and does it meet automotive quality standards?
The TPS629206QDRLRQ1 is rated -40°C to 150°C junction temperature and is AEC-Q100 Grade 0 qualified, meaning it meets the highest automotive reliability stress test requirements. This wide thermal range covers underhood mounting locations near engine blocks, exhaust-adjacent modules, and high-ambient interior installations, making it a qualified drop-in for Tier 1 automotive ECU suppliers requiring zero-defect component qualification.
