Product details
Overview
TLV62130ARGTT from Texas Instruments is a synchronous step-down DC-DC converter optimized for high-power-density POL 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) pins - used in mobile PCs, tablets, and 12-V rail supplies.
For engineers reviewing the TLV62130ARGTT datasheet, TLV62130ARGTT pinout, TLV62130ARGTT application, or TLV62130ARGTT equivalent, key selection criteria include its 3-A capability at 3–17 V input, 2.5 MHz/1.25 MHz selectable switching frequency, 19 µA quiescent current in power save mode, 100% duty cycle operation, and VQFN-16 (3 mm × 3 mm) package with exposed thermal pad.
Technical Context
The TLV62130ARGTT implements DCS-Control™ topology, combining direct output voltage sensing with a fast comparator and internal voltage feedback loop to achieve stable regulation and sub-10-µs load transient response. 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 supporting 3-A peak current.
It integrates high-side (90 mΩ) and low-side (40 mΩ) MOSFETs, features undervoltage lockout (2.7 V ±200 mV), thermal shutdown (160°C ±20°C), and open-drain PG with programmable threshold (92–98% of VOUT). The FSW pin selects between ~2.5 MHz (low) and ~1.25 MHz (high) switching frequencies, directly impacting ripple, efficiency, and inductor size trade-offs.
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 intermediate rails without external pre-regulation. |
| Output Current | Up to 3 A continuous - enables compact 3.3-V/3-A or 5-V/3-A point-of-load supplies in space-constrained designs. |
| Output Voltage Range | 0.9 V to 5.5 V adjustable - covers core logic, I/O, and analog supply requirements across modern SoCs and FPGAs. |
| Switching Frequency | ~2.5 MHz (FSW=Low) or ~1.25 MHz (FSW=High) - allows optimization between small LC filter size (2.5 MHz) and higher light-load efficiency (1.25 MHz). |
| Quiescent Current | 19 µA typical - sustains battery runtime in always-on subsystems (e.g., modem standby, sensor hubs) without compromising wake-up speed. |
| Power Good Output | Open-drain PG with 92–98% rising threshold - enables reliable power sequencing and system reset assertion in multi-rail systems. |
| Thermal Protection | 160°C shutdown with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
The TLV62130ARGTT 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 optimal thermal performance and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (1,2,3) | Switch Node | Connects to external inductor; carries high di/dt switching current - requires short, low-inductance layout to minimize ringing and EMI. |
| PVIN (11,12), PGND (15,16) | Power Input/Ground | High-current paths for power stage - must be routed with wide copper and connected directly to exposed thermal pad for thermal and electrical integrity. |
| AVIN (10), AGND (6) | Analog Supply/Ground | Provides clean bias for control circuitry - separate from power ground to reduce noise coupling into feedback and reference circuits. |
| FB (5) | Voltage Feedback | Monitors output via resistive divider - sets regulated VOUT; accuracy depends on resistor tolerance and layout symmetry near this pin. |
| SS/TR (9) | Soft-Start / Tracking | Controls startup ramp time via external capacitor; also supports voltage tracking for coordinated multi-rail sequencing. |
| EN (13) | Enable Input | Active-high logic control - internal 400-kΩ pull-down ensures safe default-off state; enables precise power-up timing and rail sequencing. |
| PG (4) | Power Good Output | Open-drain status signal - requires external pull-up; asserts high when VOUT reaches 92–98% of target, critical for system initialization. |
| DEF (8) | Output Voltage Scaling | Logic-selectable +5% margining - Low = nominal VOUT, High = VOUT+5%; supports hardware validation and voltage margin testing. |
| FSW (7) | Frequency Select | Configures switching frequency - Low ≈2.5 MHz (smaller inductors), High ≈1.25 MHz (higher light-load efficiency, lower ripple with ≥2.2 µH inductor). |
| VOS (14) | Output Voltage Sense | Remote sense input - improves regulation accuracy under load by compensating for PCB trace IR drop between regulator and load. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62130AARGTT | Same pinout and electrical specs, but PG pin actively pulls low (not high-impedance) during shutdown/UVLO - enables active VOUT discharge. | Required where controlled VOUT ramp-down is needed for system safety or data retention (e.g., industrial PLCs, medical monitors). | Select TLV62130AARGTT if active PG sink during fault conditions is mandatory; otherwise TLV62130ARGTT suffices for standard sequencing. |
| TPS62130ARGTT | Pin-compatible upgrade with improved 12-µA IQ, tighter VOUT accuracy (±1%), and enhanced thermal performance (RθJA = 38°C/W vs. 45°C/W). | Better suited for thermally constrained, ultra-low-power applications like wearable sensors or always-on IoT edge nodes. | Choose TPS62130ARGTT for new designs requiring lowest possible standby power or higher precision; TLV62130ARGTT remains valid for cost-optimized, volume production. |
Compared with TLV62130AARGTT, the TLV62130ARGTT offers simpler sequencing but lacks active discharge; versus TPS62130ARGTT, it trades 7 µA higher IQ and slightly looser accuracy for established qualification and broader distributor stock availability.

FAQ
What is the maximum continuous output current supported by the TLV62130ARGTT?
The TLV62130ARGTT supports up to 3 A continuous output current under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design with exposed pad soldered). Peak current capability reaches 4.2 A per internal current limit specification, but sustained 3-A operation requires adequate copper area and airflow to maintain junction temperature below 125°C.
Does the TLV62130ARGTT support output voltage margining, and how is it configured?
Yes, the TLV62130ARGTT supports ±5% output voltage margining via the DEF pin. When DEF is grounded (logic low), the device regulates to nominal VOUT set by the FB divider. When DEF is pulled to VOUT (logic high), output is increased to VOUT + 5%. This feature enables hardware validation of system voltage tolerance margins without changing external resistors.
How does the TLV62130ARGTT manage efficiency across varying load conditions?
The TLV62130ARGTT uses DCS-Control™ to seamlessly transition between PWM mode (fixed ~2.5 MHz or ~1.25 MHz) at medium/heavy loads and power save mode (frequency scaled linearly with load) at light loads. This maintains >85% efficiency from 1 mA to 3 A, with only 19 µA quiescent current - eliminating efficiency cliffs common in fixed-frequency converters.
Can the TLV62130ARGTT operate with input voltage close to the output voltage, and what mechanism enables this?
Yes, the TLV62130ARGTT supports 100% duty cycle operation, allowing regulation when VIN approaches VOUT. When input drops near output level, the high-side MOSFET remains continuously on, bypassing switching losses. This extends usable battery life in single-cell Li-ion applications, enabling stable 3.3-V output down to VIN ≈ 3.45 V at full 3-A load.
What thermal considerations are critical for reliable operation of the TLV62130ARGTT?
Reliable operation requires soldering the exposed thermal pad to a solid AGND/PGND plane with ≥4 thermal vias (0.3-mm diameter) connecting to inner/ground layers. With proper layout, the TLV62130ARGTT achieves RθJA = 45°C/W. Exceeding 125°C junction temperature triggers thermal shutdown at 160°C (20°C hysteresis), so board-level thermal simulation and IR imaging are recommended for 3-A continuous use.
