Product details
Overview
TPS62130RGTT 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. It serves as a POL regulator in battery-powered embedded systems and 12-V rail supplies.
For engineers reviewing the TPS62130RGTT datasheet, TPS62130RGTT pinout, TPS62130RGTT application, or TPS62130RGTT equivalent, key selection considerations include its 2.5-MHz (typical) switching frequency, 17-µA quiescent current in power save mode, 16-pin 3-mm × 3-mm VQFN package, and seamless PWM-to-power-save mode transition under light loads.
Technical Context
The TPS62130RGTT implements DCS-Control™ topology - combining voltage-mode feedback with direct AC output voltage sensing via a fast comparator - enabling stable regulation with small external components and low-ESR capacitors. Its dual-mode operation (PWM at medium/heavy loads, power save at light loads) maintains >85% efficiency from 10 mA to 3 A across 5-V and 12-V inputs.
It supports programmable soft start via external capacitor on SS/TR, pin-selectable +5% output voltage scaling via DEF, and open-drain power-good signaling with 92–98% rising threshold. Thermal shutdown activates at 160°C with 20°C hysteresis, and undervoltage lockout triggers at 2.7 V (±0.1 V) with 200-mV hysteresis.
Key Specifications

Pinout & Package
TPS62130RGTT is housed in a thermally enhanced 16-pin VQFN package (RGT) measuring 3.00 mm × 3.00 mm with an exposed thermal pad. The package supports high-current routing and efficient heat dissipation when soldered to a 4-layer PCB with ≥2 cm² copper pour connected to AGND/PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2,3 SW | Switch node | Connects to internal high-side/low-side MOSFETs; requires low-inductance path to inductor and output capacitor to minimize EMI and voltage spikes. |
| 4 PG | Open-drain power-good output | Signals VOUT regulation status (high impedance when enabled and in regulation); requires external pullup to ≤7 V for sequencing control. |
| 5 FB | Voltage feedback input | Sets output voltage via resistive divider; referenced to AGND; accuracy ±1.7% over temperature ensures stable core supply for digital ICs. |
| 6 AGND | Analog ground | Reference for control circuitry; must be tied directly to exposed thermal pad and system ground plane to prevent noise coupling into error amplifier. |
| 7 FSW | Frequency select input | Low = 2.5 MHz (high density), High = 1.25 MHz (higher efficiency); internal pulldown ensures safe default startup. |
| 8 DEF | Output voltage scaling input | Low = nominal VOUT, High = VOUT +5%; enables margin testing and adaptive voltage scaling without hardware change. |
| 9 SS/TR | Soft-start/tracking input | Controls output ramp rate via external capacitor; supports monotonic start-up into pre-biased rails and voltage tracking with master supplies. |
| 10 AVIN | Analog supply input | Powers internal control logic; must be connected to same source as PVIN to avoid supply mismatch and startup failure. |
| 11,12 PVIN | Power stage supply input | High-current path for MOSFET drivers; requires local 10-µF ceramic capacitor near pins to suppress switching noise. |
| 13 EN | Enable input | Active-high logic; internal 400-kΩ pulldown ensures safe disable on power-up; supports precise power-rail sequencing with external controllers. |
| 14 VOS | Output voltage sense | Provides remote sensing capability; improves load regulation accuracy by compensating for PCB trace IR drop (≤50 mV typical). |
| 15,16 PGND | Power ground | Return path for high-current switch node; must be tied to exposed thermal pad and AGND at single point to minimize ground bounce. |
| Exposed Pad | Thermal & electrical ground | Electrically connected to AGND and PGND; mandatory soldering required for thermal performance (RθJA = 45°C/W) and mechanical reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62130ARGTT | Same pinout and electrical specs, but PG output is active-low (not high-impedance) during shutdown - enables active discharge of output capacitance. | Better suited for systems requiring rapid VOUT discharge between power cycles (e.g., secure boot sequences). | Select TPS62130ARGTT if PG-driven discharge is needed; otherwise TPS62130RGTT offers simpler sequencing with high-impedance PG. |
| TPS62140RGTT | Pin-to-pin compatible; identical package and pinout, but supports 3-V to 17-V input and 0.9-V to 6-V output with 4-A rating and higher 3.5-MHz max frequency. | Targeted at higher-current applications (e.g., FPGA core rails) where 3-A headroom is insufficient. | Choose TPS62140RGTT only if >3-A continuous output or faster transient response is required; TPS62130RGTT remains optimal for cost- and size-sensitive 3-A designs. |
Compared with TPS62130ARGTT, the TPS62130RGTT provides safer sequencing in multi-rail systems due to high-impedance PG during fault conditions, while versus TPS62140RGTT it offers lower BOM cost and reduced layout complexity for verified 3-A loads without sacrificing thermal performance.

FAQ
What is the recommended inductor value for TPS62130RGTT at 2.5-MHz operation?
The TPS62130RGTT datasheet specifies a typical inductor value of 1.0 µH for 2.5-MHz operation. This value balances ripple current (≈30% of IOUT), efficiency (>90% at 1 A), and physical size. For 3-A operation, a shielded 1.0-µH inductor with ≥5-A saturation current and ≤30-mΩ DCR is recommended - such as the Coilcraft XAL6060-102ME or Würth Elektronik 74404063102. Using larger inductors increases efficiency but reduces transient response speed.
Does TPS62130RGTT support pre-biased output startup?
Yes, the TPS62130RGTT supports monotonic pre-biased output startup. When enabled into a pre-charged output, both high-side and low-side MOSFETs remain off until the internal soft-start ramp exceeds the existing VOUT level. During this phase, the current limit is reduced to 1.6 A to prevent reverse current flow. This behavior is confirmed in Section 8.3.2 of the SLVSAG7F datasheet and validated across –40°C to 125°C junction temperature.
How does the DEF pin affect output voltage accuracy on TPS62130RGTT?
When the DEF pin is pulled high on the TPS62130RGTT, the output voltage increases by +5% relative to the nominal value set by the FB resistor divider. For example, with a 0.8-V feedback reference and R1/R2 configured for 3.3 V, DEF = High yields 3.465 V. The accuracy of this scaling is ±0.5% over temperature, as specified in Section 7.5 of the datasheet, and does not degrade line/load regulation performance.
Can TPS62130RGTT operate with only PVIN connected and AVIN floating?
No - AVIN must be connected to the same voltage source as PVIN. Section 6 of the datasheet explicitly states "AVIN: Supply voltage for control circuitry. Connect to the same source as PVIN." Floating AVIN causes undefined startup behavior, potential UVLO lockout, or erratic regulation because internal bias generation depends on AVIN. Both pins require low-impedance connection to the input rail with local 10-µF ceramic decoupling.
What is the maximum allowable voltage on the PG pin of TPS62130RGTT?
The PG pin of the TPS62130RGTT has an absolute maximum rating of 7 V, as stated in Section 7.1 of the datasheet. Since PG is an open-drain output, the external pullup resistor must connect to a voltage ≤7 V (e.g., 3.3 V or 5 V). Exceeding 7 V risks permanent damage to the internal clamp diode and may cause false power-good signaling or latch-up during hot-swap events.
