Product details
Overview
TPS6213013AQRGTTQ1 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 with DCS-Control™ topology, 1.25 MHz/2.5 MHz selectable switching frequency, and 17 µA typical quiescent current - deployed in ADAS camera power rails where compact size and low-noise regulation are critical.
For engineers reviewing the TPS6213013AQRGTTQ1 datasheet, TPS6213013AQRGTTQ1 pinout, TPS6213013AQRGTTQ1 application, or TPS6213013AQRGTTQ1 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification (–40°C to 125°C), 1.3 V fixed output with ±1.8% accuracy in PWM mode, seamless transition between PWM and Power Save Mode, and 3 mm × 3 mm VQFN-16 package with exposed thermal pad for thermal reliability in space-constrained automotive modules.
Technical Context
The TPS6213013AQRGTTQ1 implements DCS-Control™ topology, combining a fast AC comparator loop for immediate transient response with a stable DC voltage feedback loop for precise regulation - enabling high output-voltage accuracy (±1.8%) and fast load-step recovery without external compensation. Its dual-mode operation sustains >85% efficiency at 1 mA load via Power Save Mode while maintaining constant-frequency PWM (1.25 MHz or 2.5 MHz) under medium-to-heavy loads.
It integrates internal high-side (90 mΩ typ.) and low-side (40 mΩ typ.) MOSFETs, supports 100% duty-cycle operation down to VIN ≈ VOUT + 15%, and features programmable soft-start/tracking via external capacitor on SS/TR pin - all within a single 16-pin VQFN package with separate analog (AGND) and power (PGND) ground pins for noise-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports direct connection to automotive 12-V battery rail with transient tolerance up to 17 V. |
| Output Voltage | Fixed 1.3 V ±1.8% (PWM mode) - eliminates external resistor divider, reduces BOM count and layout sensitivity. |
| Max Output Current | 3 A continuous - sufficient for powering SoCs, image sensors, or FPGA core rails in ADAS camera modules. |
| Quiescent Current | 17 µA typical - enables ultra-low standby power in always-on vehicle systems without compromising wake-up latency. |
| Switching Frequency | Selectable 1.25 MHz / 2.5 MHz via FSW pin - allows optimization of inductor size (e.g., 2.2 µH @ 1.25 MHz) vs. EMI profile. |
| Thermal Protection | 160°C junction shutdown with 20°C hysteresis - prevents thermal runaway during sustained overload or poor PCB heatsinking. |
| Power Good Output | Open-drain PG pin with 92–98% rising threshold - provides reliable sequencing signal for downstream logic or microcontrollers. |
Pinout & Package
TPS6213013AQRGTTQ1 is housed in a 3 mm × 3 mm, 16-pin VQFN package (RGT) with exposed thermal pad soldered to AGND/PGND for enhanced thermal dissipation and mechanical reliability in automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2,3 SW | Switch node | Connection point for external inductor; carries high di/dt switching current - requires short, low-inductance routing to minimize EMI. |
| 4 PG | Power good open-drain output | Indicates VOUT ≥92% nominal; requires external pullup (e.g., to 3.3 V) - used for rail sequencing or system reset assertion. |
| 5 FB | Feedback input (not used) | Internally connected for fixed 1.3 V output; must be tied to AGND per TI design guidelines to optimize thermal performance. |
| 6 AGND | Analog ground | Reference for control circuitry; must be connected directly to exposed thermal pad and common ground plane to reduce noise coupling. |
| 7 FSW | Frequency select input | Low = 2.5 MHz, High = 1.25 MHz - enables EMI tuning without changing external components. |
| 8 DEF | Output voltage scaling input | Low = 1.3 V nominal, High = 1.365 V (+5%) - allows fine-tuning for margin testing or process variation compensation. |
| 9 SS/TR | Soft-start / tracking input | External capacitor sets startup ramp time; also accepts external voltage for supply tracking in multi-rail systems. |
| 10 AVIN | Analog supply input | Provides bias for control circuitry; must be connected to same source as PVIN to avoid ground bounce. |
| 11,12 PVIN | Power stage supply input | High-current path for MOSFET drivers; requires low-ESR bulk capacitance near pins 11/12 to suppress input ripple. |
| 13 EN | Enable input | Active-high logic (VH = 0.9 V); internal 400 kΩ pulldown ensures safe default-off state - supports power sequencing. |
| 14 VOS | Output voltage sense | Direct connection to output capacitor improves regulation accuracy by compensating for PCB trace resistance. |
| 15,16 PGND | Power ground | Return path for high-current switching loops; must be tied to exposed thermal pad and AGND for thermal and EMI integrity. |

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 FB divider; same pinout, package, and DCS-Control™ engine. | Requires two external resistors and layout space for feedback network; less suitable for cost-sensitive, fixed-voltage designs. | Choose when system-level voltage margining or future design reuse across multiple output voltages is required. |
| TPS62133A-Q1 | Fixed 5-V output; identical thermal and electrical specs except output voltage and package marking (PA6JQ). | Not usable for 1.3-V core rails; intended for USB, CAN, or auxiliary 5-V supplies rather than processor cores. | Choose only if target application requires exactly 5 V - not a functional substitute for TPS6213013AQRGTTQ1's 1.3 V output. |
Compared with TPS62130A-Q1, the TPS6213013AQRGTTQ1 reduces component count and layout complexity by fixing the output at 1.3 V, while differing from TPS62133A-Q1 in both output voltage and application scope - making it uniquely suited for low-voltage SoC core regulation in automotive vision systems.

FAQ
What is the output voltage of the TPS6213013AQRGTTQ1 and how is it set?
The TPS6213013AQRGTTQ1 delivers a fixed 1.3 V output voltage, factory-programmed and internally trimmed - no external feedback resistors are required. This eliminates component count and layout sensitivity associated with adjustable regulators. The device uses an internal reference and precision amplifier to maintain ±1.8% accuracy in PWM mode, and the FB pin must be connected to AGND per TI's layout recommendations to ensure optimal thermal performance and regulation stability.
Does the TPS6213013AQRGTTQ1 support automotive qualification and functional safety requirements?
Yes, the TPS6213013AQRGTTQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C junction temperature), with HBM ±2 kV and CDM ±500 V ESD ratings. It is also functional safety-capable: TI provides documentation including FIT rate data, failure mode analysis, and diagnostic coverage reports to support ISO 26262 ASIL-B system-level development. These resources are accessible via the official TPS6213013AQRGTTQ1 product folder on ti.com.
How does the TPS6213013AQRGTTQ1 manage efficiency across light and heavy loads?
The TPS6213013AQRGTTQ1 uses DCS-Control™ to seamlessly transition between PWM mode (constant 1.25 MHz or 2.5 MHz frequency) at medium/heavy loads and Power Save Mode (frequency scaled linearly with load) at light loads - achieving >85% efficiency at 1 mA and >92% at 1 A. Its 17 µA typical quiescent current minimizes standby losses, while integrated MOSFETs with 90 mΩ/40 mΩ RDS(on) reduce conduction losses across the full 0–3 A range.
Can the TPS6213013AQRGTTQ1 be used in 100% duty-cycle applications?
Yes, the TPS6213013AQRGTTQ1 enters 100% duty-cycle mode when VIN approaches VOUT, maintaining regulation down to VIN ≈ VOUT + 0.2 V (e.g., 1.5 V input for 1.3 V output). In this mode, the high-side MOSFET remains continuously on and the low-side FET is disabled - enabling extended operation in battery-powered ADAS cameras during brownout conditions without dropout or reset.
What is the purpose of the DEF pin on the TPS6213013AQRGTTQ1?
The DEF (output voltage scaling) pin on the TPS6213013AQRGTTQ1 allows dynamic adjustment of the output voltage: pulling DEF low maintains the nominal 1.3 V output, while pulling it high increases output to 1.365 V (+5%). This feature supports margin testing, process corner validation, or temporary overvoltage for improved timing margins during system bring-up - without requiring hardware changes.
