Product details
Overview
TLV62130ARGTR 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, features DCS-Control™ topology for fast transient response, and integrates power good (PG), soft-start/tracking (SS/TR), and frequency select (FSW) functions - used in POL supplies for tablets, motor drives, and set-top boxes.
For engineers reviewing the TLV62130ARGTR datasheet, TLV62130ARGTR pinout, TLV62130ARGTR application, or TLV62130ARGTR equivalent, key selection criteria include its 3-A capability at 17-V max input, 19-µA quiescent current in power save mode, 2.5-MHz/1.25-MHz selectable switching frequency, 100% duty cycle operation, and VQFN-16 (3 mm × 3 mm) thermal-pad package.
Technical Context
The TLV62130ARGTR implements DCS-Control™ topology, combining direct output voltage sensing with a fast comparator and internal compensation to achieve stable regulation and sub-10-µs load transient response without external loop compensation. Its dual-mode operation-PWM at medium/heavy loads and seamless transition to power save mode at light loads-maintains >85% efficiency down to 1 mA while preserving low output ripple.
It integrates high-side (90 mΩ) and low-side (40 mΩ) MOSFETs, supports programmable soft start via external capacitor on SS/TR, enables voltage margining via DEF pin (nominal or +5%), and provides open-drain PG with 92–98% rising threshold for rail sequencing - all within a thermally enhanced 16-pin VQFN package with exposed thermal pad connected to AGND and PGND.
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, FPGA I/O, or motor driver bias rails. |
| Output Voltage Range | 0.9 V to 5.5 V adjustable - covers DDR memory, microcontroller cores, and analog subsystems. |
| Quiescent Current | 19 µA typical - enables >1000-hour battery life in always-on IoT sensor nodes. |
| Switching Frequency | Selectable: 2.5 MHz (FSW=Low) or 1.25 MHz (FSW=High) - balances size (small inductor) vs. efficiency (lower loss). |
| Power Good Output | Open-drain PG with 92–98% rising threshold - enables reliable multi-rail power sequencing in embedded systems. |
| Thermal Protection | 160°C shutdown with 20°C hysteresis - prevents damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
TLV62130ARGTR is housed in a 16-pin VQFN package (RGT) measuring 3.00 mm × 3.00 mm with an exposed thermal pad soldered to AGND/PGND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (1,2,3) | Switch node | Connects internal high-/low-side MOSFETs to external inductor; requires low-inductance layout to minimize EMI. |
| PGND (15,16) | Power ground | Must be directly tied to exposed thermal pad and main ground plane to handle 3-A return currents. |
| AGND (6) | Analog ground | Reference for FB, PG, and control circuitry; isolated from noisy PGND except at thermal pad. |
| PVIN (11,12) | Power stage supply | Provides gate drive and power FET bias; connect close to input capacitor with low-impedance path. |
| AVIN (10) | Analog supply | Bias for error amplifier and logic; tie to same source as PVIN but decoupled separately. |
| FB (5) | Voltage feedback | Resistive divider sets output voltage; high-impedance input (≤100 nA leakage) minimizes divider error. |
| EN (13) | Enable control | Active-high logic; internal 400-kΩ pull-down ensures safe default-off state if left floating. |
| SS/TR (9) | Soft-start/tracking | External capacitor sets startup ramp time; also accepts external voltage for precise rail tracking. |
| DEF (8) | Output voltage scaling | Low = nominal VOUT, High = VOUT+5% - enables hardware margining without firmware change. |
| FSW (7) | Frequency select | Low = ~2.5 MHz (compact design), High = ~1.25 MHz (higher efficiency, lower ripple). |
| PG (4) | Power good indicator | Open-drain output requiring external pull-up; asserts high impedance when disabled or in fault. |
| VOS (14) | Output voltage sense | Direct connection to output capacitor improves regulation accuracy under load transients. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Enables stable regulation with small ceramic capacitors and no external compensation components. |
| Seamless PWM-to-power-save transition | Maintains regulated output and <10-mV droop during mode switch - critical for noise-sensitive RF circuits. |
| 100% duty cycle operation | Allows VOUT regulation down to VIN – 0.3 V (e.g., 3.3 V out from 3.6 V Li-ion), extending battery runtime. |
| Programmable soft start | Prevents inrush current into large output capacitance - avoids brownout of upstream supplies. |
| Integrated short-circuit protection | Reduces current limit to 1.6 A when VOUT < 0.5 V, preventing thermal runaway during output faults. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62130AARGTR | Same pinout and specs, but PG pin asserts Low (not high-impedance) during shutdown - enables active VOUT discharge. | Required where controlled power-down sequencing or rapid rail collapse is needed (e.g., FPGA configuration reset). | Select TLV62130AARGTR only if active PG sink behavior is required; otherwise TLV62130ARGTR offers simpler pull-up implementation. |
| TPS62130ARGTR | Pin-compatible upgrade with improved 15-µA IQ, tighter ±0.5% VOUT accuracy, and enhanced thermal performance (RθJA = 38°C/W). | Suitable for new designs demanding higher precision or lower standby power, but not drop-in for legacy TLV62130 layouts due to different PG logic timing. | Choose TPS62130ARGTR for next-gen designs; verify PG timing compatibility with host sequencer before migration. |
Compared with TLV62130ARGTR, TLV62130AARGTR adds active discharge capability at the cost of requiring external pull-up for normal operation, while TPS62130ARGTR delivers measurable improvements in accuracy and efficiency but necessitates validation of power-good timing margins in existing systems.

FAQ
What is the maximum input voltage rating for TLV62130ARGTR?
The absolute maximum input voltage for TLV62130ARGTR is 20 V, but the recommended operating range is 3 V to 17 V. Exceeding 17 V continuously may trigger undervoltage lockout recovery instability or accelerate parametric drift. The device enters UVLO shutdown below 2.6 V and resumes operation only after VIN rises above 2.8 V due to 200-mV hysteresis - ensuring robust operation across battery discharge curves. TLV62130ARGTR maintains regulation integrity within this window under all load and temperature conditions specified in its datasheet.
Does TLV62130ARGTR support pre-biased output startup?
Yes, TLV62130ARGTR supports monotonic pre-biased output startup. When enabled into a pre-charged rail, the low-side MOSFET remains off until the internal soft-start ramp exceeds the present output voltage, preventing reverse current flow. During this phase, the current limit is reduced to 1.6 A to limit stress on external components. This behavior is confirmed in the device's functional description and startup waveforms (Figure 32/33 of SLVSB74H). TLV62130ARGTR achieves clean, non-drooping startup even with 3.3-V pre-bias on a 1.2-V output rail.
How does the FSW pin affect efficiency and output ripple in TLV62130ARGTR?
When FSW is pulled Low, TLV62130ARGTR operates at ~2.5 MHz, enabling smaller inductors (e.g., 1 µH) and lower output ripple (<15 mVpp) but with 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, increasing inductor RMS current and ripple (~35 mVpp with 2.2 µH), yet improving full-load efficiency to 94% by reducing gate charge and switching losses. TLV62130ARGTR's datasheet specifies both configurations with validated test data across temperature and line/load conditions.
What is the purpose of the VOS pin on TLV62130ARGTR?
The VOS (Voltage Output Sense) pin on TLV62130ARGTR provides Kelvin sensing of the output voltage directly at the load side of the output capacitor, improving regulation accuracy under dynamic load conditions. It connects to the positive terminal of the output capacitor and feeds the control loop independently of FB, compensating for PCB trace resistance and inductor DCR voltage drop. This dual-sensing architecture allows TLV62130ARGTR to maintain ±1% output accuracy over line, load, and temperature - critical for powering precision analog circuits or high-speed memory interfaces.
Can TLV62130ARGTR operate in 100% duty cycle mode, and what are the practical limits?
Yes, TLV62130ARGTR enters 100% duty cycle mode when VIN approaches VOUT, turning on the high-side MOSFET continuously to sustain regulation - e.g., 3.3 V output from a 3.6-V Li-ion cell. The minimum functional VIN is approximately VOUT + (IOUT × RDS(on)_HS), so at 3 A and 90 mΩ, it can regulate down to ~3.57 V. Below this, dropout occurs. This mode extends usable battery life by >15% compared to fixed-frequency buck converters lacking 100% duty cycle capability, as confirmed in TLV62130ARGTR's efficiency vs. input voltage plots.
