Product details
Overview
TPS629206QDRLRQ1 from Texas Instruments is an AEC-Q100 qualified automotive synchronous buck converter delivering up to 600 mA output current with 4 µA typical quiescent current, 3 V to 17 V input range, ±1% output voltage accuracy, and DCS-Control topology for seamless PWM/PFM transition. It serves as a primary power supply for ADAS sensors and infotainment domain controllers.
For engineers reviewing the TPS629206QDRLRQ1 datasheet, TPS629206QDRLRQ1 pinout, TPS629206QDRLRQ1 application, or TPS629206QDRLRQ1 equivalent, key selection considerations include its AEC-Q100 Level 2 qualification, 2.5-MHz/1.0-MHz selectable switching frequency, internal/external feedback configuration flexibility via MODE/S-CONF and FB/VSET pins, and integrated power-good and thermal shutdown protection.
Technical Context
The TPS629206QDRLRQ1 implements TI's DCS-Control topology with internal compensation, enabling fast transient response and stable operation with low-ESR ceramic capacitors. Its control loop directly feeds output voltage changes to a fast comparator while maintaining precise DC regulation via a voltage feedback network.
It supports dual operating modes-forced PWM (1.0 MHz or 2.5 MHz) and auto PFM/PWM-with dynamic mode change capability when configured by logic level on MODE/S-CONF. The device integrates high-side (250 mΩ) and low-side (85 mΩ) MOSFETs, 100% duty cycle support, and Smart-CONFIG resistor-based setup for output voltage, frequency, discharge, and mode selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - Supports direct connection to 12-V automotive battery rails, 5-V/3.3-V subsystems, and single/multi-cell Li-ion sources without pre-regulation. |
| Output Current | 0.6 A - Sufficient for powering microcontrollers, image sensors, CAN transceivers, and display drivers in ADAS and body electronics. |
| Quiescent Current | 4 µA - Enables >10-year battery standby life in always-on vehicle modules such as radar wake-up circuits and telematics keep-alive functions. |
| Output Voltage Accuracy | ±1% at TJ = 0°C–85°C - Ensures reliable core voltage regulation for automotive SoCs and FPGAs without external trimming. |
| Switching Frequency | Selectable 1.0 MHz or 2.5 MHz - Allows EMI optimization: 2.5 MHz enables compact 2.2-µH inductor + 22-µF output capacitor layout; 1.0 MHz improves light-load efficiency in low-power domains. |
| RDS(on) | 250 mΩ (HS), 85 mΩ (LS) - Minimizes conduction loss across wide temperature range (–40°C to +150°C), supporting high-efficiency operation in engine bay environments. |
| Protection Features | Overcurrent (1.1–1.7 A HS limit), overtemperature (170°C shutdown), UVLO (2.95 V rising), and power-good - Provides fault containment for safety-critical automotive subsystems. |
Pinout & Package
TPS629206QDRLRQ1 uses an 8-pin SOT-5X3 package (1.60 mm × 2.10 mm, 0.5-mm pitch) optimized for high-density automotive PCB layouts and thermally efficient mounting on small copper pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB/VSET | Voltage feedback or internal VSET selection | Configurable pin: connects to external divider for adjustable output (0.6 V–5.5 V) or to GND/resistor for factory-programmed VOUT (0.4 V–5.5 V, 18 options). |
| PG | Open-drain power-good indicator | Signals valid regulation (93–99% of target VOUT); used for rail sequencing in multi-supply systems like instrument clusters and ADAS ECUs. |
| VOS | Output voltage sense | Direct connection to output capacitor positive terminal enables accurate remote sensing and compensates for PCB trace IR drop. |
| SW | Switch node | Connects to internal HS/LS FETs and external inductor; requires tight layout with minimal loop area to reduce EMI and switching losses. |
| GND | Power ground | Primary return path for high-current switching; must be connected to solid thermal pad under package for optimal thermal performance. |
| VIN | Main input supply | Accepts 3–17 V; requires local 4.7-µF ceramic capacitor placed adjacent to pin to suppress high-frequency input ripple. |
| EN | Enable/disable control | Precision threshold (0.9–1.03 V) allows RC-delayed startup or programmable undervoltage lockout; internal pulldown prevents floating. |
| MODE/S-CONF | Mode selection & Smart-CONFIG | Dual-function: logic level selects forced PWM vs auto PFM; resistor value configures frequency, VSET/FB mode, and discharge enable at boot. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Combines hysteretic speed with voltage-mode stability-enables <10-µs load transient response and eliminates need for external compensation components. |
| AEC-Q100 Grade 2 qualification | Validated for –40°C to +150°C junction operation, HBM ±2 kV, CDM ±750 V-meets functional safety requirements for ASIL-B system power rails. |
| Smart-CONFIG resistor interface | Single external resistor on MODE/S-CONF pin sets switching frequency, feedback method (VSET/FB), discharge enable, and PFM/PWM behavior-reduces BOM count and design iterations. |
| Internal/external feedback flexibility | VSET mode offers 18 factory-trimmed outputs (0.4 V–5.5 V) without external resistors; FB mode supports precision adjustable regulation (0.6 V–5.5 V) with standard divider networks. |
| Integrated power-good and discharge | PG output enables safe multi-rail sequencing; active discharge (7.5–20 Ω) ensures rapid, controlled VOUT ramp-down during disable-critical for EEPROM write integrity and FPGA configuration retention. |

The TPS629206QDRLRQ1 supports two configuration methods: (1) External feedback via resistor divider connected to FB/VSET pin for adjustable outputs from 0.6 V to 5.5 V; or (2) Internal VSET mode using a single resistor from FB/VSET to GND to select one of 18 factory-trimmed outputs between 0.4 V and 5.5 V, as defined in Table 8-2 of the datasheet.
What protection features are integrated into the TPS629206QDRLRQ1?
The TPS629206QDRLRQ1 integrates overcurrent protection (1.1–1.7 A high-side limit), overtemperature shutdown (+170°C), input undervoltage lockout (2.95 V rising threshold), power-good monitoring, and output discharge. These features collectively ensure robust operation in automotive environments subject to load dumps, cranking, and thermal stress.
