Product details
Overview
TPS62130ARGTR from Texas Instruments is a synchronous step-down DC-DC converter optimized for high-power-density applications, delivering up to 3 A continuous output current with input voltage range 3 V to 17 V, adjustable output voltage from 0.9 V to 6 V, and DCS-Control™ topology for fast transient response-used in POL supplies for embedded systems and solid-state drives.
For engineers reviewing the TPS62130ARGTR datasheet, TPS62130ARGTR pinout, TPS62130ARGTR application, or TPS62130ARGTR equivalent, key selection considerations include its 2.5 MHz (typical) switching frequency, 17 µA quiescent current in power save mode, 100% duty cycle capability, integrated power-good output, and thermal/short-circuit protection for reliable operation in battery-powered and 12-V rail systems.
Technical Context
The TPS62130ARGTR implements DCS-Control™ topology-a hybrid regulation scheme combining voltage-mode feedback with direct AC output sensing-to achieve tight DC regulation and sub-100 ns load-step response while maintaining seamless transition between PWM and power save modes. Its internal error amplifier, comparator-based ramp control, and fixed on-time circuitry enable stable operation with low-ESR ceramic capacitors and small inductors.
It supports dual-frequency operation (1.25 MHz / 2.5 MHz) via FSW pin, programmable soft-start/tracking via SS/TR pin, and ±5% output voltage margining via DEF pin. Power sequencing is enabled through coordinated EN and open-drain PG signaling, with thermal shutdown at 160°C and undervoltage lockout at 2.7 V (200 mV hysteresis).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports single/multi-cell Li-ion batteries and standard 12-V intermediate rails without external pre-regulation. |
| Output Current | Up to 3 A continuous - sufficient for powering SoCs, FPGAs, and SSD controllers in compact layouts. |
| Switching Frequency | Typically 2.5 MHz (FSW = Low) - enables use of ≤1 µH inductors and <22 µF ceramic output capacitance for minimal footprint. |
| Quiescent Current | 17 µA (typical) - maintains high light-load efficiency in always-on subsystems like modem standby or sensor hubs. |
| Output Voltage Accuracy | ±1.7% over temperature - ensures stable core voltage delivery for processors requiring tight VDD tolerance. |
| Thermal Shutdown | 160°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design without latch-off behavior. |
| Power Good Output | Open-drain PG with 92–98% rising threshold - provides reliable rail sequencing signal for multi-rail systems without external comparators. |
Pinout & Package
TPS62130ARGTR is housed in a thermally enhanced 3 mm × 3 mm, 16-pin VQFN package (RGT) with exposed thermal pad soldered to AGND/PGND for optimal heat dissipation and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2,3 SW | Switch node | Connects to inductor; carries high di/dt switching current-requires short, low-inductance routing to minimize ringing and EMI. |
| 4 PG | Power good indicator | Open-drain output; requires external pullup to ≤7 V; asserts high impedance when EN=Low, UVLO active, or thermal shutdown. |
| 5 FB | Feedback input | Senses output voltage divider ratio; sets regulated VOUT for adjustable versions; connect to AGND on fixed-output variants. |
| 6 AGND | Analog ground | Reference for control circuitry; must be tied directly to exposed thermal pad and system ground plane to avoid noise coupling. |
| 7 FSW | Frequency select | Pull Low for 2.5 MHz (high density), High for 1.25 MHz (higher efficiency); internal 400 kΩ pulldown ensures default high-frequency mode. |
| 8 DEF | Voltage margining | Set Low for nominal VOUT, High for +5%; enables hardware-level voltage margin testing without firmware changes. |
| 9 SS/TR | Soft-start/tracking | External capacitor sets startup ramp time; also accepts external voltage for supply tracking during power-up/down sequences. |
| 10 AVIN | Analog supply | Provides bias for control logic; tie to same source as PVIN but route separately to reduce noise injection into sensitive analog blocks. |
| 11,12 PVIN | Power stage input | High-current path for MOSFET drivers; requires low-ESR bulk capacitance near pins to suppress input ripple and voltage sag. |
| 13 EN | Enable input | Active-High logic; internal 400 kΩ pulldown ensures safe default disable; supports precise power sequencing with other rails. |
| 14 VOS | Voltage sense | Direct connection to output for improved loop stability and accuracy; used internally for DCS-Control compensation network. |
| 15,16 PGND | Power ground | Return path for high-current switch node; must be connected to exposed thermal pad and common ground to minimize ground bounce. |
| Exposed Pad | Thermal & electrical ground | Electrically tied to AGND and PGND; mandatory soldering required for thermal performance (>4.5°C/W junction-to-board). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62140ARGTR | Pin-to-pin compatible; fixed 1.2-V output; identical 3-A rating, 3–17-V input, and DCS-Control™ architecture. | Eliminates external feedback resistors but lacks output adjustability-suitable only where 1.2 V is required. | Select when fixed 1.2-V core supply is needed and layout reuse is prioritized over flexibility. |
| TPS62150ARGTR | Pin-to-pin compatible; fixed 1.8-V output; same thermal specs and protection features; shares identical RGT package. | Optimized for 1.8-V I/O or memory rails; no DEF/SS/TR programmability-reduces BOM count but removes margining capability. | Choose for 1.8-V applications like DDR termination or interface buffers where voltage tuning is unnecessary. |
Compared with TPS62130ARGTR, the TPS62140ARGTR and TPS62150ARGTR offer identical packaging, thermal performance, and protection-but trade adjustable output and voltage margining for simplified fixed-voltage implementation, making them ideal drop-in replacements only when their specific output voltages match system requirements.

FAQ
What is the maximum output current capability of the TPS62130ARGTR?
The TPS62130ARGTR delivers up to 3 A continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 12 V, VOUT = 3.3 V). Peak current limit is 4.2 A (typical), with reduced 1.6 A short-circuit protection below 0.5 V output. Thermal performance depends on PCB layout and copper area-achieving full 3 A requires proper thermal pad soldering and ≥2 oz copper on inner layers.
Does the TPS62130ARGTR support power sequencing with other voltage rails?
Yes, the TPS62130ARGTR supports robust power sequencing via its EN and open-drain PG pins. EN can be driven by another rail's PG signal to enforce turn-on order, while PG provides a timing-accurate "VOUT ready" flag (92–98% threshold) to trigger downstream enables. The SS/TR pin further enables voltage tracking for synchronized ramp-up/down across multiple converters in the same system.
How does the DCS-Control™ topology in the TPS62130ARGTR improve transient response?
The DCS-Control™ topology in the TPS62130ARGTR combines a fast comparator-based AC loop (directly sensing output voltage changes) with a precision voltage feedback loop. This dual-path architecture achieves <10 µs transient recovery with <1% droop-significantly faster than conventional voltage-mode controllers-while maintaining stability with small ceramic capacitors and no external compensation components.
Can the TPS62130ARGTR operate with input voltage close to the output voltage?
Yes, the TPS62130ARGTR supports 100% duty cycle operation, allowing it to maintain regulation when VIN drops to within ~15% above VOUT (e.g., 3.6 V input for 3.3 V output). In this mode, the high-side MOSFET remains continuously on, minimizing conduction loss and maximizing battery runtime in portable applications where input voltage sags under load.
What are the key thermal design requirements for the TPS62130ARGTR?
The TPS62130ARGTR requires soldering of its exposed thermal pad to a solid AGND/PGND plane with ≥4 thermal vias (0.3 mm diameter) connecting to inner ground layers. TI specifies RθJA = 45°C/W and RθJCbot = 4.5°C/W-achieving rated 3-A output demands ≥250 mm² of 2-oz copper on the top layer and adequate internal ground planes. Poor thermal design risks premature thermal shutdown at >125°C junction temperature.
