Product details
Overview
TPS629210QDRLRQ1 from Texas Instruments is an AEC-Q100 qualified automotive synchronous buck converter delivering up to 1 A output current with 4-µA typical quiescent current, ±1% output voltage accuracy, and 3-V to 17-V input range. It operates in DCS-Control topology with seamless PWM/PFM transition and supports 0.4-V to 5.5-V output via internal VSET or external FB divider - used in ADAS power rails requiring low IQ and high reliability.
For engineers reviewing the TPS629210QDRLRQ1 datasheet, TPS629210QDRLRQ1 pinout, TPS629210QDRLRQ1 application, or TPS629210QDRLRQ1 equivalent, key selection criteria include its AEC-Q100 Level 2 qualification, 2.5-MHz/1-MHz configurable switching frequency, MODE/S-CONF programmable configuration, integrated power-good output, and dual-package availability (DRL/DYC) for thermal-sensitive automotive layouts.
Technical Context
The TPS629210QDRLRQ1 implements TI's DCS-Control topology with internal compensation, enabling fast transient response and stable regulation using small ceramic capacitors. Its control loop directly senses output voltage changes via a fast comparator while maintaining constant-frequency operation in steady state.
It integrates a 250-mΩ high-side and 85-mΩ low-side MOSFET pair, supports 100% duty cycle operation, and features Smart-CONFIG via the MODE/S-CONF pin for simultaneous selection of switching frequency, feedback mode (VSET vs FB), output discharge, and PFM/PWM behavior - all determined at startup without runtime reconfiguration when resistor-programmed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports direct connection to 12-V automotive battery, 5-V/3.3-V rails, or multi-cell Li-ion sources without pre-regulation. |
| Output Current | Up to 1 A - sufficient for powering radar SoCs, display controllers, or microcontrollers in body electronics and ADAS modules. |
| Quiescent Current | 4 µA typical - enables >10-year battery standby life in always-on vehicle systems such as telematics or intrusion detection. |
| Output Voltage Accuracy | ±1% at TJ = 0°C to 85°C - ensures precise rail regulation for sensitive analog sensors and ADC references. |
| Switching Frequency | Configurable 1.0 MHz or 2.5 MHz - allows optimization between EMI filtering size (higher fSW) and light-load efficiency (lower fSW). |
| RDS(on) | 250 mΩ (HS), 85 mΩ (LS) - minimizes conduction loss and thermal rise in compact SOT-5X3 packages under full load. |
| Protection Features | Overcurrent (1.5–2.1 A HS limit), overtemperature (170°C shutdown), UVLO (2.95 V rising), and power-good output - enables robust fault handling in unattended automotive environments. |
Pinout & Package
TPS629210QDRLRQ1 is packaged in an 8-pin SOT-5X3 (DRL) package measuring 1.60 mm × 2.10 mm, optimized for high-density automotive PCBs with exposed thermal pad for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB/VSET | Voltage feedback or internal VSET selection | Configurable pin: connects to external resistor for 18 fixed outputs (0.4 V–5.5 V) or to resistive divider for adjustable regulation (0.6 V–5.5 V). |
| PG | Open-drain power-good indicator | Signals valid output regulation; requires external pull-up; used for sequencing multiple rails in infotainment or cluster systems. |
| VOS | Output voltage sense | Direct connection to output capacitor positive terminal enables accurate remote sensing and improves load regulation. |
| SW | Switch node | Connects internally to both MOSFETs; requires low-inductance layout to minimize EMI and switching losses. |
| GND | Power ground | Primary return path for high-current switching loop; must be tied to thermal pad and adjacent to VIN and SW for minimal loop area. |
| VIN | Input supply | Accepts 3–17 V; requires local 4.7-µF ceramic capacitor placed within 2 mm of pin to suppress high-frequency ripple. |
| EN | Enable with precision threshold | Starts/stops conversion; rising threshold = 0.97 V, falling = 0.9 V - enables programmable undervoltage lockout using resistor divider. |
| MODE/S-CONF | Configuration and mode selection | Resistor-programmable pin that sets switching frequency, feedback mode, discharge enable, and PFM/PWM behavior at startup. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Combines hysteretic speed with voltage-mode stability - achieves <10-µs transient response and eliminates need for external compensation components. |
| Auto Efficiency Enhancement (AEE) | Dynamically adjusts switching frequency based on VIN/VOUT to maintain >90% efficiency across 10 µA–1 A load range without inductor swapping. |
| Pin-to-pin compatibility | Direct replacement for TPS629206-Q1 (0.6 A) and TPS629203-Q1 (0.3 A) - enables scalable power design with shared layout and BOM reuse. |
| No bootstrap capacitor required | Integrated charge pump eliminates external capacitor - reduces bill-of-materials count and PCB footprint in space-constrained modules. |

FAQ
What is the maximum output current capability of the TPS629210QDRLRQ1?
The TPS629210QDRLRQ1 delivers up to 1 A of continuous output current under recommended operating conditions (TJ ≤ 150°C, proper thermal layout). Its overcurrent protection triggers at 1.5–2.1 A (high-side) depending on temperature, allowing brief surge tolerance during startup or transient events without latch-off.
Does the TPS629210QDRLRQ1 require an external bootstrap capacitor?
No, the TPS629210QDRLRQ1 does not require an external bootstrap capacitor. It integrates an internal charge pump circuit that self-generates the gate drive voltage for the high-side MOSFET - simplifying layout, reducing component count, and eliminating a common source of reliability risk in automotive applications.
How is output voltage configured on the TPS629210QDRLRQ1?
The TPS629210QDRLRQ1 supports two configuration methods: (1) External feedback via FB/VSET pin using a resistive divider 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 from 0.4 V to 5.5 V - both methods are set at startup and remain fixed during operation.
What thermal packages are available for the TPS629210QDRLRQ1?
The TPS629210QDRLRQ1 is offered in two SOT-5X3 variants: DRL (standard 8-pin) and DYC (pin-compatible variant). Both measure 1.60 mm × 2.10 mm, but the DYC package delivers lower thermal resistance - RθJA = 55°C/W (vs 60°C/W for DRL on same EVM) - making it preferable for high-ambient or high-power-density automotive modules.
Is the TPS629210QDRLRQ1 pin-compatible with other devices in the family?
Yes, the TPS629210QDRLRQ1 is pin-to-pin compatible with the TPS629206QDRLRQ1 and TPS629203QDRLRQ1. This enables scalable power design: engineers can use the same PCB layout for 0.3-A, 0.6-A, or 1-A versions - simplifying qualification, reducing NRE, and accelerating time-to-market across vehicle platforms.
