Product details
Overview
TPS62130AQRGTRQ1 from Texas Instruments is an automotive-grade synchronous step-down DC-DC converter with DCS-Control™ topology, 3-V to 17-V input range, adjustable 0.9-V to 6-V output, and 3-A continuous output current. It delivers high efficiency (up to 95% at 1 A, VIN = 12 V, VOUT = 3.3 V), 17 µA quiescent current, and operates at 1.25 MHz or 2.5 MHz selectable switching frequency - used in ADAS camera power rails requiring stable, low-noise, compact voltage regulation.
For engineers reviewing the TPS62130AQRGTRQ1 datasheet, TPS62130AQRGTRQ1 pinout, TPS62130AQRGTRQ1 application, or TPS62130AQRGTRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), seamless PWM-to-Power Save Mode transition, programmable soft-start/tracking, and integrated power-good output for rail sequencing.
Technical Context
The TPS62130AQRGTRQ1 implements DCS-Control™ - a hybrid regulation architecture combining fast AC response via direct output-voltage sensing with stable DC regulation via internal error amplifier feedback. This enables sub-10-µs transient response and <±1.8% output voltage accuracy in PWM mode.
It supports dual-frequency operation (1.25 MHz / 2.5 MHz) via FSW pin control, 100% duty-cycle mode for ultra-low dropout (e.g., 3.6-VIN → 3.3-VOUT), and robust protection including thermal shutdown (160°C), undervoltage lockout (2.7 V ±0.1 V), and short-circuit current limiting (4.2 A typical peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports wide automotive battery and intermediate bus rails without pre-regulation. |
| Output Voltage Range | 0.9 V to 6 V (adjustable via FB resistor divider) - enables single IC across multiple SoC core/I/O rail requirements. |
| Max Output Current | 3 A continuous - sustains full load under worst-case thermal conditions (RθJA = 45°C/W). |
| Quiescent Current | 17 µA typical - extends battery runtime in always-on vehicle modules (e.g., telematics wake-up circuits). |
| Switching Frequency | 1.25 MHz or 2.5 MHz (pin-selectable) - balances EMI performance vs. inductor size (e.g., 2.2 µH @ 2.5 MHz fits 3×3 mm layout). |
| Efficiency Peak | 95% at 1 A, VIN = 12 V, VOUT = 3.3 V - minimizes thermal stress in sealed ADAS enclosures. |
| Power Good Accuracy | ±3% window (92–98% VOUT) - ensures reliable sequencing with downstream processors and FPGAs. |
Pinout & Package
TPS62130AQRGTRQ1 is housed in a thermally enhanced 3-mm × 3-mm VQFN-16 package (RGT) with exposed thermal pad soldered to AGND/PGND for optimal power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN (1,2,3) | Power input for high-current path | Connects directly to input capacitor and inductor - separate from AVIN to isolate noise-sensitive analog circuitry. |
| PG (4) | Open-drain power-good indicator | Sinks 2 mA; asserts LOW when VOUT drops below 92% nominal - used for FPGA reset coordination or multi-rail enable sequencing. |
| FB (5) | Feedback node for output voltage regulation | Internal 0.8-V reference; external resistor divider sets VOUT - enables precise adjustment without trimming. |
| AGND (6) | Analog ground reference | Must be tied to exposed thermal pad and system AGND plane - critical for DCS-Control™ loop stability and noise immunity. |
| FSW (7) | Frequency select input | LOW = 2.5 MHz, HIGH = 1.25 MHz - allows EMI tuning without changing BOM or layout. |
| DEF (8) | Output voltage scaling input | LOW = nominal VOUT, HIGH = VOUT + 5% - supports margin testing or dynamic voltage scaling in infotainment SoCs. |
| SS/TR (9) | Soft-start and tracking control | External capacitor sets ramp time; voltage injection enables synchronized startup with master rail - prevents backfeed in multi-converter systems. |
| AVIN (10) | Analog supply input | Provides clean bias for control logic - must tie to same source as PVIN but routed separately to minimize coupling. |
| EN (13) | Enable/disable control | Active-HIGH with 0.65-V threshold; internal 400-kΩ pulldown - simplifies power sequencing with microcontroller GPIO or PMIC signals. |
| VOS (14) | Output voltage sense | Remote sensing point - improves regulation accuracy under PCB trace IR drop (e.g., long traces to camera sensor). |
| PGND (15,16) | Power ground return | High-current return path for SW node - must connect to exposed thermal pad and low-impedance ground plane to limit ripple and EMI. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62150AQRGTRQ1 | Pin-to-pin compatible; identical package, pinout, and control features; differs in max output current (2 A vs. 3 A) and input range (3–17 V same). | Lower current rating limits use in >2-A loads (e.g., high-res camera ISPs); suitable for cost-sensitive telematics modules with lighter processing loads. | Select when 2-A output suffices and board reuse is prioritized over peak performance. |
| LM61480QRNXTQ1 | Higher 8-A rating, 2.1-MHz fixed frequency, different pinout (16-pin WQFN), no DEF/SS/TR pins; requires layout change and new compensation design. | Targets high-power domain controllers (e.g., ADAS central compute); lacks tracking/soft-start flexibility needed for sequenced multi-rail systems. | Choose only when scaling to >3-A loads; not a drop-in replacement due to non-compatible pin mapping and control interface. |
Compared with TPS62130AQRGTRQ1, TPS62150AQRGTRQ1 offers identical integration and footprint at reduced current capacity, while LM61480QRNXTQ1 trades configurability for raw power - making the TPS62130AQRGTRQ1 optimal for balanced performance, flexibility, and space-constrained automotive modules.

FAQ
What is the maximum continuous output current of the TPS62130AQRGTRQ1?
The TPS62130AQRGTRQ1 delivers 3 A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). This rating is validated across the full –40°C to +125°C junction temperature range and accounts for internal MOSFET RDS(on) (90 mΩ high-side, 40 mΩ low-side at VIN ≥ 6 V) and thermal resistance (RθJA = 45°C/W).
Does the TPS62130AQRGTRQ1 support power sequencing with other voltage rails?
Yes, the TPS62130AQRGTRQ1 supports robust power sequencing via its EN (enable) and open-drain PG (power good) pins. The PG pin asserts LOW when VOUT falls below 92% of nominal and HIGH when regulation is achieved within ±3%, enabling cascaded enable timing. Combined with SS/TR pin tracking capability, it allows synchronized startup with master supplies in multi-rail automotive systems.
How does the DCS-Control™ topology in the TPS62130AQRGTRQ1 improve transient response?
The DCS-Control™ topology in the TPS62130AQRGTRQ1 uses direct output voltage sensing to feed an ultra-fast comparator, enabling sub-10-µs response to load steps. Unlike traditional voltage-mode control, it avoids phase-margin constraints from external compensation - maintaining stability with low-ESR ceramic capacitors and achieving <±15 mV deviation during 1-A/µs transients at 3.3 V output.
Can the TPS62130AQRGTRQ1 operate during automotive cold-crank conditions?
Yes, the TPS62130AQRGTRQ1 supports cold-crank operation via its 100% duty-cycle mode, which maintains regulation down to VIN ≈ VOUT + (IOUT × RDS(on)). At 3.3-V output and 2-A load, it sustains regulation with VIN as low as ~3.6 V - well within ISO 16750-2 cold-crank minimum (6.5 V for 12-V systems, but extended to lower voltages in some hybrid architectures).
What is the purpose of the VOS pin on the TPS62130AQRGTRQ1?
The VOS (voltage output sense) pin on the TPS62130AQRGTRQ1 provides remote sensing capability - connecting directly to the load side of output trace impedance to compensate for IR drop. This ensures tight output voltage regulation (<±1.8%) at the point-of-load, critical for noise-sensitive imaging sensors and high-speed serial interfaces in automotive ADAS applications.
