Product details
Overview
TPS62097QWRGTRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified synchronous step-down DC/DC converter optimized for automotive power rails. It delivers up to 2 A output current, supports 2.5 V to 6.0 V input, provides adjustable 0.8 V to VIN output voltage with ±1% accuracy, and achieves up to 97% efficiency at 1.8 V/2 A output in forced PWM mode - deployed in instrument clusters and telematics modules.
For engineers reviewing the TPS62097QWRGTRQ1 datasheet, TPS62097QWRGTRQ1 pinout, TPS62097QWRGTRQ1 application, or TPS62097QWRGTRQ1 equivalent, key selection criteria include iDCS-Control topology behavior, wettable-flank QFN thermal performance, MODE pin-configurable 1.5–2.5 MHz switching, soft-start programmability via SS/TR, and integrated hiccup short-circuit protection.
Technical Context
The TPS62097QWRGTRQ1 implements iDCS-Control - a predictive on-time architecture enabling seamless transition between PWM and Power Save Mode (PSM) or forced PWM-only operation. Its internal compensation supports >150 µF output capacitance, and the 100% duty cycle mode maintains regulation down to VIN ≈ VOUT + IOUT × (RDS(on)HS + DCR).
Switching frequency is set during power-up MODE detection (tMODE ≈ 50 µs) via resistor or AGND connection; once locked, it remains fixed. The device integrates output discharge (165 Ω), power good (open-drain, 92–98% VOUT threshold), and thermal shutdown (160°C, 20°C hysteresis) with automatic recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 6.0 V - supports wide automotive battery transients including cold-crank (≥2.5 V) and load-dump (≤6.0 V). |
| Output Current | Up to 2.0 A continuous - sufficient for SoC core rails and high-speed interface supplies in gateway ECUs. |
| Output Voltage Accuracy | ±1% in PWM mode - ensures stable logic-level compliance for 1.8 V, 2.5 V, or 3.3 V domains without external trimming. |
| Peak Efficiency | 97% at 1.8 V/2 A, VIN = 5.0 V - minimizes thermal stress in sealed automotive enclosures. |
| Switching Frequency | Selectable 1.5 MHz to 2.5 MHz - enables compact magnetics while avoiding AM band interference in head units. |
| Quiescent Current | 57 µA typical - extends battery life during vehicle sleep modes without compromising wake-up response. |
| Thermal Shutdown | 160°C junction, 20°C hysteresis - protects against sustained overload or poor PCB heatsinking in instrument clusters. |
Pinout & Package
TPS62097QWRGTRQ1 uses a 3.0 mm × 3.0 mm, 16-pin QFN package with wettable flanks (RGT) and exposed thermal pad connected to AGND. Anchor pins (1, 4, 12, 16) require soldering for mechanical reliability but no electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOS | Output voltage sense | Direct connection to output capacitor cathode - enables accurate remote sensing and fast transient response. |
| FB | Feedback input | Accepts resistor divider for adjustable output; internally biased at 0.8 V reference - sets VOUT = 0.8 V × (1 + R1/R2). |
| MODE | Mode selection | Configures PWM/PSM auto-transition (AGND) or forced PWM only (resistor/open) - determines noise vs. light-load efficiency trade-off. |
| SS/TR | Soft-start/voltage tracking | Charged by 7.5 µA current for controlled ramp-up; externally driven for sequencing - supports ratiometric or coincidental rail tracking. |
| PG | Power good open-drain | Sinks ≤1 mA when VOUT < 90% nominal; high-Z above 95% - enables safe multi-rail power sequencing in ADAS domain controllers. |
| EN | Enable input | Logic-high active with 375 kΩ internal pull-down - allows direct MCU GPIO control and supports low-power disable (<1 µA shutdown current). |
| SW | Switch node | Connects to inductor - carries high di/dt; requires tight layout to minimize EMI in infotainment systems. |
| PGND / AGND | Power / analog ground | Separate ground pins reduce noise coupling into feedback path - critical for maintaining ±1% regulation under dynamic load. |
Key Features
| Feature | Design Value |
|---|---|
| iDCS-Control topology | Enables seamless PWM-to-PSM transition without output voltage disturbance - essential for noise-sensitive audio amplifiers and camera ISPs. |
| Wettable flanks QFN (3 mm × 3 mm) | Enables automated optical inspection (AOI) of solder joints - improves manufacturing yield for automotive Tier-1 production. |
| Hiccup short-circuit protection | Triggers after 32 overcurrent events, then auto-restarts after 100 µs - limits fault energy during connector shorting in wiring harnesses. |
| Programmable soft-start | Startup time set by external capacitor on SS/TR (tSS ≈ 0.85 × CSS × VIN) - prevents inrush-induced brownout in shared 5 V supply rails. |
| Output discharge | 165 Ω internal FET discharges VOUT when EN = low - ensures clean power-down sequencing for FPGA configuration memory. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6209733QWRGTRQ1 | Fixed 3.3 V output; FB pin recommended to connect to AGND; identical package and pinout. | No external resistor divider required - reduces BOM count and layout area for fixed-voltage designs. | Select when 3.3 V output is required and design simplicity outweighs adjustability. |
| LMQ66430QRNXTQ1 | 3.0 A output, 4.2 V to 36 V input, integrated MOSFETs, 2.1 MHz fixed frequency, lower quiescent current (15 µA). | Higher input range suits 24 V commercial vehicles; higher current supports dual-core processors. | Select for wider VIN range or higher current needs; not drop-in due to different pinout and control scheme. |
Compared with TPS62097QWRGTRQ1, the TPS6209733QWRGTRQ1 offers identical thermal and functional behavior but eliminates output adjustment flexibility, while the LMQ66430QRNXTQ1 trades adjustability and footprint for extended input range and higher current - neither is pin-compatible, requiring PCB redesign.

FAQ
What is the maximum output current supported by the TPS62097QWRGTRQ1?
The TPS62097QWRGTRQ1 supports up to 2.0 A continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 2.5 V to 6.0 V). Peak current capability reaches 3.6 A before hiccup protection triggers. Derating applies at elevated ambient temperatures or with insufficient PCB copper area for thermal dissipation - full 2 A output requires ≥200 mm² of 2-oz copper connected to the exposed thermal pad.
Does the TPS62097QWRGTRQ1 support fixed output voltage configurations?
The TPS62097QWRGTRQ1 itself is the adjustable-output variant (0.8 V to VIN); however, TI offers the pin-compatible TPS6209733QWRGTRQ1 for fixed 3.3 V output. Both share identical package, thermal characteristics, and feature set - only the internal feedback network differs. For TPS62097QWRGTRQ1, fixed outputs require external resistor dividers per VOUT = 0.8 V × (1 + R1/R2).
How does the MODE pin affect switching behavior in the TPS62097QWRGTRQ1?
The MODE pin configures operation during power-up detection (≈50 µs window): tied to AGND enables automatic PWM/PSM transition; left open or pulled to PVIN via resistor selects forced PWM only. Forced PWM maintains constant frequency (1.5–2.5 MHz) for EMI control, while PWM/PSM improves light-load efficiency at the cost of variable frequency. Once set, the mode cannot be changed dynamically without cycling EN.
Can the TPS62097QWRGTRQ1 be used in 12 V automotive systems?
Yes - the TPS62097QWRGTRQ1 accepts up to 6.0 V input, so it must be used downstream of a pre-regulator (e.g., 12 V → 5 V) in standard 12 V automotive systems. Its 2.5 V minimum input supports cold-crank operation after pre-regulation. Direct 12 V input would exceed absolute maximum ratings and cause permanent damage to the TPS62097QWRGTRQ1.
What is the purpose of the VOS pin on the TPS62097QWRGTRQ1?
The VOS (Voltage Output Sense) pin on the TPS62097QWRGTRQ1 provides Kelvin sensing of the output voltage directly at the load-side of the output capacitor. Connecting VOS to the capacitor's cathode (not the SW node) improves regulation accuracy under dynamic load and compensates for PCB trace resistance - critical for maintaining ±1% output accuracy in high-current automotive applications.
