Product details
Overview
TPS6213013AQRGTRQ1 from Texas Instruments is an automotive-grade, 3-V to 17-V input, 1.3-V fixed-output synchronous step-down DC-DC converter delivering up to 3 A continuous output current. It features DCS-Control™ topology, 1.25 MHz / 2.5 MHz selectable switching frequency, 17 µA quiescent current in power save mode, and integrated power good (PG) output. It is used in ADAS camera power rails requiring stable low-noise 1.3-V supply with fast transient response.
For engineers reviewing the TPS6213013AQRGTRQ1 datasheet, TPS6213013AQRGTRQ1 pinout, TPS6213013AQRGTRQ1 application, or TPS6213013AQRGTRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to 125°C), 100% duty-cycle capability for battery-drop scenarios, seamless PWM-to-PSM transition, and fixed 1.3-V output with ±1.8% accuracy in PWM mode.
Technical Context
The TPS6213013AQRGTRQ1 implements DCS-Control™-a hybrid regulation architecture combining voltage-mode feedback with direct output-voltage sensing via a fast comparator and internal ramp generator. This enables precise DC regulation while delivering immediate transient response without external compensation.
It supports dual-frequency operation (1.25 MHz or 2.5 MHz) via the FSW pin, enters power save mode automatically below light-load thresholds, and maintains regulation down to 100% duty cycle when VIN approaches VOUT. Its integrated PG open-drain output provides rail-ready status with programmable threshold hysteresis (92–98% rising, 87–94% falling).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports wide automotive bus rails including 12-V and 14-V systems with cold-crank margin. |
| Output Voltage | Fixed 1.3 V ±1.8% (PWM mode) - eliminates external feedback resistors; optimized for core logic or SerDes I/O in ADAS processors. |
| Max Output Current | 3 A continuous - sustains full load under worst-case thermal conditions (TJ ≤ 125°C) with proper PCB layout. |
| Quiescent Current | 17 µA typical - enables always-on subsystems (e.g., camera wake-on-motion) without excessive battery drain. |
| Switching Frequency | Selectable 1.25 MHz / 2.5 MHz - higher frequency allows smaller 2.2-µH inductors; lower frequency improves light-load efficiency. |
| Thermal Protection | 160°C shutdown with 20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| Power Good Threshold | Rising: 92–98% of VOUT; Falling: 87–94% - ensures reliable sequencing with downstream logic and avoids false resets. |
Pinout & Package
TPS6213013AQRGTRQ1 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 and EMI control.
| 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 reduce noise coupling into control circuitry. |
| PG (4) | Open-drain power-good indicator | Sinks 2 mA when VOUT is out-of-regulation; requires external pullup to enable rail sequencing or system reset coordination. |
| FB (5) | Feedback reference node | Internally tied to fixed 1.3-V divider; connect to AGND per datasheet for thermal stability in fixed-output variants. |
| AGND (6) | Analog ground reference | Must be connected to exposed thermal pad and common ground plane to minimize control-loop noise and offset error. |
| FSW (7) | Frequency select input | Low = 2.5 MHz, High = 1.25 MHz; internal pulldown ensures default 2.5 MHz if left floating. |
| DEF (8) | Output voltage scaling | Low = nominal 1.3 V, High = 1.365 V (+5%); used for margin testing or adaptive voltage scaling in specific applications. |
| SS/TR (9) | Soft-start/tracking control | External capacitor sets startup ramp time; also accepts external voltage for synchronized power-up with master rail. |
| AVIN (10) | Analog supply input | Provides clean bias for control circuitry; tie to same source as PVIN but route separately to avoid switching noise injection. |
| EN (13) | Enable/disable control | Active-high logic; internal 400-kΩ pulldown ensures safe default-off state; supports multi-rail sequencing via upstream regulator outputs. |
| VOS (14) | Output voltage sense | Direct connection to output capacitor for accurate remote sensing; improves load regulation under PCB trace resistance. |
| PGND (15,16) | Power ground return | High-current return path for SW node; must be tied to exposed thermal pad and AGND at single-point star ground. |
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 |
|---|---|---|---|
| TPS62130A-Q1 | Adjustable output (0.9–6 V) via external resistor divider; identical pinout, package, and DCS-Control™ engine. | Requires external FB resistors; suitable for designs needing multiple output voltages from same footprint. | Choose when flexibility in output voltage tuning outweighs BOM simplification from fixed 1.3 V. |
| TPS62133A-Q1 | Fixed 5-V output; same thermal performance, protection features, and AEC-Q100 Grade 1 rating. | Targets 5-V microcontroller peripherals or USB host controllers instead of low-voltage digital cores. | Use where 5-V rail consolidation is needed; not interchangeable due to different output voltage and DEF pin behavior. |

FAQ
What is the output voltage tolerance of the TPS6213013AQRGTRQ1 under PWM operation?
The TPS6213013AQRGTRQ1 has a guaranteed output voltage accuracy of ±1.8% over temperature and line/load conditions when operating in PWM mode (VIN ≥ VOUT + 1 V). This specification applies to the fixed 1.3-V output and is verified across the full AEC-Q100 Grade 1 temperature range (–40°C to +125°C). The TPS6213013AQRGTRQ1 achieves this using factory-trimmed internal feedback and DCS-Control™'s fast transient correction, eliminating need for external calibration.
Does the TPS6213013AQRGTRQ1 support power sequencing with other rails?
Yes, the TPS6213013AQRGTRQ1 supports robust power sequencing through its EN (enable) and PG (power good) pins. The EN pin accepts active-high logic to coordinate startup timing, while the open-drain PG output signals VOUT readiness (high impedance when valid, pulled low during fault or shutdown). When paired with upstream regulators, the TPS6213013AQRGTRQ1 can be configured to power up only after primary rails stabilize, ensuring safe SoC initialization in multi-rail automotive systems.
Can the TPS6213013AQRGTRQ1 operate with input voltage as low as the output voltage?
Yes, the TPS6213013AQRGTRQ1 supports 100% duty-cycle operation, enabling regulation even when VIN drops to within ~15% above VOUT (e.g., VIN ≈ 1.5 V for 1.3-V output). In this mode, the high-side MOSFET remains continuously on, and the low-side FET is disabled. This feature extends runtime in battery-powered ADAS cameras during cold-crank or deep-discharge events, maintaining core logic functionality until VIN recovers.
What is the recommended inductor value for the TPS6213013AQRGTRQ1 at 1.25 MHz operation?
Texas Instruments recommends a 2.2-µH shielded power inductor (e.g., Coilcraft XFL4020-222MEB) for TPS6213013AQRGTRQ1 operation at 1.25 MHz. This value balances peak current ripple (~30% of IOUT), thermal performance, and board space constraints. At 1.25 MHz, the 2.2-µH inductor yields ~1.2-A peak-to-peak ripple at 3-A load, aligning with the device's current limit and DCS-Control™ stability requirements. Lower inductance increases ripple and conduction loss; higher inductance reduces ripple but degrades transient response.
Is the TPS6213013AQRGTRQ1 pin-compatible with other devices in the TPS6213xA-Q1 family?
Yes, the TPS6213013AQRGTRQ1 shares identical pinout, package (VQFN-16 RGT), and footprint with TPS62130A-Q1 and TPS62133A-Q1. All three devices use the same 3-mm × 3-mm land pattern and thermal pad layout. However, output voltage configuration differs: TPS6213013AQRGTRQ1 is fixed at 1.3 V, TPS62133A-Q1 at 5 V, and TPS62130A-Q1 is adjustable. Swapping requires verifying FB/DEF connections and output capacitor ratings to match the target voltage.
