Product details
Overview
TLV62130RGTT from Texas Instruments is a synchronous step-down DC-DC converter optimized for high-power-density applications. It operates from 3 V to 17 V input, delivers up to 3 A continuous output current, supports adjustable output voltage from 0.9 V to 5.5 V, and features DCS-Control™ topology for fast transient response-used in POL supplies for Li-ion battery-powered tablets and motor drives.
For engineers reviewing the TLV62130RGTT datasheet, TLV62130RGTT pinout, TLV62130RGTT application, or TLV62130RGTT equivalent, key selection criteria include its 2.5 MHz (or 1.25 MHz) selectable switching frequency, 19 µA quiescent current in power save mode, integrated power good output, and 3 mm × 3 mm VQFN-16 package with thermal pad.
Technical Context
The TLV62130RGTT implements DCS-Control™ topology-a hybrid regulation scheme combining voltage-mode feedback with direct output voltage sensing to enable seamless transition between PWM and power save modes. Its control loop uses an internal ramp and fast comparator to achieve immediate load transient response while maintaining stable DC regulation via a compensated error amplifier.
It integrates dual MOSFET power switches with 90 mΩ high-side and 40 mΩ low-side RDS(on), supports 100% duty cycle operation for ultra-low dropout, and includes undervoltage lockout (2.7 V threshold), thermal shutdown (160 °C), and short-circuit protection with reduced 1.6 A current limit below 0.5 V output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports single/dual Li-ion batteries and standard 12-V rails without external pre-regulation. |
| Output Current | Up to 3 A continuous - sufficient for core logic rails in mobile PCs and point-of-sale systems. |
| Switching Frequency | 1.25 MHz or 2.5 MHz (pin-selectable) - enables compact 2.2 µH inductor use at lower frequency or minimal 1 µH at higher frequency. |
| Quiescent Current | 19 µA typical - sustains >85% efficiency at 1 mA load, critical for always-on subsystems. |
| Output Voltage Range | 0.9 V to 5.5 V (adjustable via FB divider) - covers I/O, core, and analog supply requirements across multiple SoCs. |
| Power Good Output | Open-drain PG with 92–98% rising threshold - enables reliable sequencing of downstream FPGAs or processors. |
| Thermal Protection | 160 °C shutdown with 20 °C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
TLV62130RGTT is housed in a 3 mm × 3 mm, 16-pin VQFN package (RGT) with exposed thermal pad soldered to AGND/PGND for optimal thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (1,2,3) | Switch node | Connects to inductor; carries high di/dt switching current - requires short, low-inductance layout to minimize ringing. |
| PGND (15,16) | Power ground | Low-impedance return path for high-current switch node - must be tied directly to thermal pad and separate from AGND plane. |
| AGND (6) | Analog ground | Reference for FB, SS/TR, and control circuitry - connected to thermal pad but isolated from noisy PGND at single-point star ground. |
| FB (5) | Voltage feedback input | Senses output via resistive divider; sets regulation point - sensitive to noise; requires local 100 pF bypass near pin. |
| EN (13) | Enable input | Active-high logic control; internal 400 kΩ pull-down ensures safe default-off state - used for rail sequencing. |
| PG (4) | Power good open-drain output | Indicates VOUT ≥95% nominal; requires external pull-up - signals system controller when supply is stable. |
| SS/TR (9) | Soft-start/tracking input | Controls startup ramp time via external capacitor; also accepts external voltage for supply tracking - prevents inrush into pre-biased loads. |
| DEF (8) | Output voltage scaling select | Low = nominal VOUT, High = VOUT +5% - enables hardware margining without changing resistor network. |
| FSW (7) | Frequency select input | Low = ~2.5 MHz, High = ~1.25 MHz - trade-off between solution size (higher fsw) and efficiency/ripple (lower fsw). |
| VOS (14) | Output voltage sense | Direct connection to output for improved regulation accuracy - used with remote sensing in high-current designs. |
| PVIN (11,12) | Power stage input | High-current VIN path for MOSFET drivers - routed separately from AVIN to reduce coupling into control circuitry. |
| AVIN (10) | Analog supply input | Provides clean bias for internal regulators and comparators - must be decoupled with 1 µF ceramic near pin. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Enables <10 µs load transient response with <1% undershoot/overshoot using only 22 µF output capacitance. |
| Seamless power save mode | Maintains >85% efficiency from 1 mA to 3 A without audible switching noise or output voltage discontinuity. |
| Programmable soft start | External capacitor on SS/TR pin sets monotonic startup slope - prevents inrush into hot-plugged peripherals or pre-biased rails. |
| 100% duty cycle operation | Extends battery runtime by regulating down to VIN − VDS(on)·IOUT, e.g., 3.3 V output from 3.6 V Li-ion cell. |
| Integrated power good | Open-drain PG with precise 95% threshold eliminates need for external supervisor IC in FPGA/CPU power sequencing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62130ARGTT | Same pinout and electrical specs, but PG output is active-low (not high-impedance) during shutdown - enables active discharge of output capacitor. | Better suited for systems requiring controlled VOUT ramp-down during power-off sequencing. | Select TLV62130ARGTT if PG must sink current during EN=Low or UVLO; otherwise TLV62130RGTT offers simpler pull-up-only interface. |
| TPS62130RGTT | Pin-compatible upgrade with improved 15 µA IQ, tighter ±0.5% VOUT accuracy, and enhanced thermal performance (RθJA = 40 °C/W). | Ideal for next-gen designs where lowest standby power and highest precision are mandatory. | Choose TPS62130RGTT for new designs targeting extended battery life and tighter regulation; TLV62130RGTT remains valid for cost-sensitive legacy replacements. |
Compared with TLV62130ARGTT, TLV62130RGTT provides safer default-open PG behavior during fault conditions; compared with TPS62130RGTT, it trades minor IQ and accuracy degradation for established qualification and broader distributor stock availability.

FAQ
What is the maximum output current capability of the TLV62130RGTT?
The TLV62130RGTT supports up to 3 A continuous output current under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). Peak current capability reaches 4.2 A before current limiting engages, but sustained operation above 3 A requires careful thermal management using the exposed thermal pad and adequate copper area.
Does TLV62130RGTT support output voltage adjustment below 1 V?
No. The TLV62130RGTT has a minimum regulated output voltage of 0.9 V, as specified in its electrical characteristics table. Attempting to set VOUT below 0.9 V via FB divider will result in loss of regulation, since the internal reference and error amplifier are not characterized or guaranteed below that threshold.
How does the FSW pin affect efficiency and output ripple in TLV62130RGTT?
When FSW is pulled low, TLV62130RGTT operates at ~2.5 MHz, yielding smaller inductors and capacitors but higher switching losses - typical peak efficiency is 92% at 12 V→3.3 V/2 A. When FSW is high, frequency drops to ~1.25 MHz, reducing switching losses and improving full-load efficiency to ~94%, though output ripple increases unless inductance is raised to ≥2.2 µH.
Can TLV62130RGTT safely start into a pre-biased output?
Yes. TLV62130RGTT supports monotonic pre-biased startup: the low-side MOSFET remains off until the internal soft-start ramp exceeds the pre-existing output voltage. During this phase, current limit is reduced to 1.6 A to prevent reverse current flow, ensuring safe and controlled turn-on without damaging downstream circuitry.
What is the role of the VOS pin in TLV62130RGTT, and when should it be used?
The VOS (Voltage Output Sense) pin provides remote sensing capability for improved load regulation. It should be connected directly to the load side of the output capacitor when long PCB traces introduce significant IR drop (>20 mV). Using VOS compensates for this drop, maintaining ±0.5% output accuracy at the load instead of at the IC's output pin.
