Product details
Overview
TPS629210QDYCRQ1 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 ultra-low IQ and high thermal reliability.
For engineers reviewing the TPS629210QDYCRQ1 datasheet, TPS629210QDYCRQ1 pinout, TPS629210QDYCRQ1 application, or TPS629210QDYCRQ1 equivalent, key selection criteria include its AEC-Q100 Level 2 qualification, -40°C to 150°C junction temperature operation, 2.5-MHz/1.0-MHz selectable switching frequency, internal compensation, and pin-to-pin compatibility with TPS629206-Q1 and TPS629203-Q1 for scalable power design.
Technical Context
The TPS629210QDYCRQ1 implements TI's DCS-Control topology, combining fast comparator-based transient response with a stable voltage feedback loop and internal compensation - eliminating need for external loop components. Its control architecture enables automatic efficiency enhancement (AEE) mode, dynamically adjusting switching frequency based on VIN and VOUT to sustain high efficiency across load and input conditions without inductor swapping.
Configuration is managed through the MODE/S-CONF pin, supporting dual functionality: dynamic mode toggling (forced PWM vs auto PFM) or resistor-programmed static configuration (switching frequency, VSET/FB selection, output discharge enable). The FB/VSET pin serves either as feedback input (external divider) or VSET programming node (18 fixed output options), while VOS provides remote output voltage sensing for improved regulation accuracy.
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 stacks without pre-regulation. |
| Output Current | Up to 1 A - sufficient for powering radar SoCs, camera ISPs, and infotainment microcontrollers in compact layouts. |
| Quiescent Current | 4 µA typical - enables >10-year battery standby life in always-on vehicle modules like door controllers or occupancy sensors. |
| Output Voltage Accuracy | ±1% at TJ = 0°C–85°C - ensures reliable logic-level compliance for 1.2-V, 1.8-V, and 3.3-V digital loads under nominal conditions. |
| Switching Frequency | Selectable 1.0 MHz or 2.5 MHz - allows trade-off between EMI filtering size (higher fSW → smaller LC) and light-load efficiency (lower fSW → reduced switching loss). |
| RDS(on) | 250 mΩ (HS), 85 mΩ (LS) - minimizes conduction loss at full load, enabling >90% peak efficiency at 12-V input / 3.3-V output. |
| Thermal Rating | -40°C to +150°C junction - validated for under-hood placement in engine control units and powertrain ECUs per AEC-Q100 Level 2. |
Pinout & Package
TPS629210QDYCRQ1 uses the 0.5-mm pitch, 8-pin SOT-5X3 package (DYC variant), measuring 1.60 mm × 2.10 mm including pins. This thermally enhanced package supports high-power density designs in space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB/VSET | Feedback or VSET configuration input | Dual-mode pin: connects to external resistor divider for adjustable VO or to GND/resistor for one of 18 factory-trimmed outputs (0.4 V–5.5 V). |
| PG | Open-drain power-good output | Signals valid output regulation (93–99% of target); requires external pull-up; used for rail sequencing in multi-voltage systems. |
| VOS | Remote output voltage sense | Connects directly to output capacitor positive terminal to compensate for PCB trace IR drop and improve load regulation. |
| SW | Switch node | Internal high-side/low-side MOSFET connection point; requires low-inductance layout to minimize EMI and switching losses. |
| GND | Power ground | Primary return path for power and control circuits; must be tied to thermal pad for optimal thermal performance. |
| VIN | Input supply | Accepts 3–17 V; requires local 4.7-µF ceramic capacitor placed adjacent to pin to suppress high-frequency noise. |
| EN | Enable with precision threshold | Starts/stops conversion with 0.9–1.03 V rising threshold; internal pulldown prevents floating; supports RC-delayed power-up. |
| MODE/S-CONF | Mode selection & Smart-CONFIG input | Configures switching frequency, PFM/PWM mode, and output discharge via resistor value (7.5 kΩ–249 kΩ) or logic level. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS629206QDRCRQ1 | 0.6-A output current, identical pinout and feature set except lower current rating and no 18-V absolute max input rating. | Suitable for lower-power domains like body control modules or telematics, but not for 1-A radar or infotainment SoCs. | Select when system load stays below 600 mA and cost optimization is prioritized over headroom. |
| TPS629203QDRCRQ1 | 0.3-A output current, same package and control architecture, but reduced RDS(on) (350 mΩ HS / 120 mΩ LS) and lower thermal capability. | Targeted at ultra-low-power always-on nodes (e.g., smart key receivers, tire pressure monitors) where 300-mA peak suffices. | Choose only for sub-300-mA applications where footprint and functional overlap justify reuse of existing layout. |
Compared with TPS629206QDRCRQ1 and TPS629203QDRCRQ1, the TPS629210QDYCRQ1 provides 67% higher output current and tighter thermal derating margin - making it the sole option among the three for 1-A continuous automotive loads requiring AEC-Q100 Level 2 compliance and 150°C operation.

FAQ
What is the maximum input voltage rating for the TPS629210QDYCRQ1?
The TPS629210QDYCRQ1 has an absolute maximum input voltage rating of 18 V, with recommended operating range from 3 V to 17 V. This allows safe operation during automotive load-dump events (ISO 7637-2 Pulse 5a) and cold-crank conditions down to 3 V, making it suitable for direct battery connection in engine bay and chassis-mounted modules.
Does the TPS629210QDYCRQ1 require an external bootstrap capacitor?
No, the TPS629210QDYCRQ1 integrates a charge pump that eliminates the need for an external bootstrap capacitor. This simplifies layout, reduces BOM count, and improves reliability in space-constrained automotive applications such as camera modules and radar sensors where board area is at a premium.
How does the MODE/S-CONF pin configure output voltage on the TPS629210QDYCRQ1?
The MODE/S-CONF pin on the TPS629210QDYCRQ1 determines whether FB/VSET operates in feedback (external divider) or VSET (internal 18-option) mode. When a resistor (e.g., 34.0 kΩ) is connected to MODE/S-CONF, the device reads VSET configuration at startup and selects corresponding output voltage (e.g., 1.8 V) - no further changes possible without cycling EN.
What is the purpose of the VOS pin on the TPS629210QDYCRQ1?
The VOS pin on the TPS629210QDYCRQ1 provides remote output voltage sensing by connecting directly to the positive terminal of the output capacitor. This compensates for IR drop across PCB traces, ensuring ±1% regulation accuracy at the load rather than at the IC's output pin - essential for high-current, distributed power architectures.
Is the TPS629210QDYCRQ1 pin-to-pin compatible with other devices in its family?
Yes, the TPS629210QDYCRQ1 is pin-to-pin compatible with the TPS629206-Q1 and TPS629203-Q1 in the same SOT-5X3 package. This enables scalable power design: engineers can reuse layout and firmware while upgrading from 0.3-A or 0.6-A versions to the 1-A TPS629210QDYCRQ1 for higher-performance subsystems.
