Product details
Overview
TPS62130AQRGTTQ1 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 3.3 V/1 A) and supports seamless PWM-to-Power Save Mode transition in ADAS camera power rails.
For engineers reviewing the TPS62130AQRGTTQ1 datasheet, TPS62130AQRGTTQ1 pinout, TPS62130AQRGTTQ1 application, or TPS62130AQRGTTQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to 125°C), 17 µA quiescent current, 1.25/2.5 MHz selectable switching frequency, and integrated power good (PG) output for rail sequencing.
Technical Context
The TPS62130AQRGTTQ1 implements DCS-Control™-a hybrid regulation topology combining voltage-mode feedback with direct output-voltage sensing via a fast comparator, enabling immediate transient response and stable operation with low-ESR ceramic capacitors. Its internal compensation eliminates external loop components.
It operates in PWM mode at fixed 1.25 MHz or 2.5 MHz (FSW-pin selectable), transitions seamlessly to Power Save Mode below light-load thresholds, and maintains regulation down to 100% duty cycle when VIN approaches VOUT-critical for battery-backed automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports wide automotive bus rails including 12 V nominal and cold-crank transients. |
| Output Current | 3 A continuous - sustains full load across –40°C to 125°C junction temperature without derating. |
| Quiescent Current | 17 µA typical - enables always-on functionality in infotainment telematics with minimal standby power loss. |
| Switching Frequency | 1.25 MHz or 2.5 MHz (FSW-selectable) - balances EMI control and inductor size; 2.5 MHz enables <2.2 µH inductors. |
| Output Accuracy | ±1.8% in PWM mode - ensures reliable ADC reference and sensor biasing in ADAS camera modules. |
| Power Good Output | Open-drain PG with 92–98% rising threshold - provides precise enable sequencing for multi-rail SoC power-up. |
| Thermal Protection | 160°C shutdown with 20°C hysteresis - prevents thermal runaway during sustained overload in enclosed ECUs. |
Pinout & Package
TPS62130AQRGTTQ1 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 reduce noise coupling into control circuitry. |
| PG (4) | Open-drain power good indicator | Sinks 2 mA when VOUT drops below 92% of setpoint; requires external pullup for sequencing logic. |
| FB (5) | Voltage feedback node | Connects to resistive divider for adjustable output; internal 0.8 V reference enables 0.9–6 V programming. |
| AGND (6) | Analog ground reference | Must be tied to exposed thermal pad and system AGND plane to stabilize error amplifier and reference. |
| FSW (7) | Frequency select input | Low = 2.5 MHz, High = 1.25 MHz - sets switching frequency without external clock source. |
| DEF (8) | Output voltage scaling input | Low = nominal VOUT, High = VOUT +5% - enables dynamic voltage scaling for processor DVFS. |
| SS/TR (9) | Soft-start/tracking control | External capacitor sets ramp time; voltage injection enables tracking of master supply during power-up. |
| AVIN (10) | Analog supply input | Provides clean bias for control circuitry; must tie to same source as PVIN but routed separately. |
| EN (13) | Enable input | Active-high with 0.65 V threshold; internal 400 kΩ pulldown ensures safe default-off state. |
| VOS (14) | Output voltage sense | Direct connection to output for improved load regulation; bypasses FB divider for precision sensing. |
| PGND (15,16) | Power ground return | High-current return path for SW node; must connect to exposed thermal pad and low-impedance ground plane. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62133AQRGTTQ1 | Fixed 5 V output; identical pinout, package, and DCS-Control™ architecture. | No external feedback divider required; simplified layout for dedicated 5 V rails like USB or CAN. | Select when fixed 5 V output suffices and board space for resistor network must be minimized. |
| TPS62150AQRGTTQ1 | Pin-to-pin compatible; supports 2.5 V to 6 V output range and 2.2 MHz switching frequency. | Lower minimum input voltage (2.5 V) enables wider battery discharge range; optimized for ultra-low-VIN scenarios. | Choose for systems requiring deeper battery discharge support below 3 V, such as 2-cell Li-ion backup supplies. |
Compared with TPS62133AQRGTTQ1 and TPS62150AQRGTTQ1, the TPS62130AQRGTTQ1 offers the broadest output adjustability (0.9–6 V) and highest input voltage tolerance (17 V), making it optimal for flexible multi-rail designs where programmability and transient resilience are prioritized over fixed-output simplicity or ultra-low-VIN operation.

FAQ
What is the maximum continuous output current of the TPS62130AQRGTTQ1?
The TPS62130AQRGTTQ1 delivers 3 A continuous output current across its full operating junction temperature range of –40°C to 125°C. This rating is maintained without external derating when used with proper PCB thermal design-including connection of the exposed thermal pad to AGND and PGND planes-and with recommended input/output capacitors per the datasheet.
Does the TPS62130AQRGTTQ1 support 100% duty cycle operation, and under what conditions?
Yes, the TPS62130AQRGTTQ1 enters 100% duty cycle mode when the input voltage approaches the output voltage-specifically when VIN falls to approximately 15% above VOUT. In this mode, the high-side MOSFET remains continuously on, enabling regulation during automotive cold-crank events where input may dip to near-output levels, while the low-side FET is disabled.
How does the DCS-Control™ topology in the TPS62130AQRGTTQ1 improve transient response compared to standard voltage-mode control?
The DCS-Control™ topology in the TPS62130AQRGTTQ1 integrates a fast comparator that directly monitors output voltage changes and feeds them into the switching control loop-bypassing traditional error amplifier delay. This enables sub-10 µs transient recovery with minimal output deviation, even with small 22 µF ceramic output capacitors, unlike conventional voltage-mode controllers requiring larger bulk capacitance and complex compensation networks.
Can the TPS62130AQRGTTQ1 be used in power supply tracking configurations, and how is it implemented?
Yes, the TPS62130AQRGTTQ1 supports voltage tracking via its SS/TR pin. Applying a ramp voltage (e.g., from another regulator's SS pin) to SS/TR causes the TPS62130AQRGTTQ1's output to follow that ramp-both during startup and shutdown. This enables precise sequencing of multiple rails, such as coordinating 1.2 V core and 3.3 V I/O supplies in automotive SoCs without external tracking ICs.
What are the key differences between the TPS62130AQRGTTQ1 and the pin-compatible TPS62150AQRGTTQ1?
The TPS62130AQRGTTQ1 and TPS62150AQRGTTQ1 share identical pinout and package but differ in input voltage range (TPS62130AQRGTTQ1: 3–17 V; TPS62150AQRGTTQ1: 2.5–6 V) and output adjustability (TPS62130AQRGTTQ1: 0.9–6 V; TPS62150AQRGTTQ1: 2.5–6 V). The TPS62130AQRGTTQ1 also features higher input voltage tolerance for 12 V automotive bus resilience, while the TPS62150AQRGTTQ1 targets lower-VIN battery-powered applications.
