Product details
Overview
TLV62130RGTR 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 across an input range of 3 V to 17 V, with adjustable output voltage from 0.9 V to 5.5 V and DCS-Control™ topology for fast transient response. It operates at 2.5 MHz (FSW = Low) or 1.25 MHz (FSW = High), features power good (PG) output, 100% duty cycle mode, and 19 µA quiescent current in Power Save Mode - used in POL supplies for Li-ion battery-powered tablets and motor drives.
For engineers reviewing the TLV62130RGTR datasheet, TLV62130RGTR pinout, TLV62130RGTR application, or TLV62130RGTR equivalent, key selection criteria include verified 3-A output capability at 17-V max input, confirmed DCS-Control™ loop stability with low-ESR capacitors, validated thermal performance in 3×3 mm VQFN, and functional distinction between TLV62130 (high-impedance PG during shutdown) and TLV62130A (active-low PG).
Technical Context
The TLV62130RGTR implements DCS-Control™ topology - combining hysteretic, voltage-mode, and current-mode control elements - with a direct AC path from output voltage ripple to a fast comparator that sets switching frequency and enables sub-10-µs load transient response. Its dual-mode operation (PWM at medium/heavy loads, seamless transition to Power Save Mode at light loads) maintains >85% efficiency down to 1 mA while preserving regulation accuracy.
It integrates high-side (90 mΩ typical) and low-side (40 mΩ typical) MOSFETs, supports programmable soft-start via external capacitor on SS/TR, and provides pin-selectable output scaling (+5% via DEF pin). The 16-pin VQFN package includes dedicated PVIN/AVIN rails, exposed thermal pad tied to AGND/PGND, and open-drain PG with 92–98% rising threshold and 2 mA sink capability.
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. |
| Max Output Current | 3 A continuous - sustained under thermal limits with proper PCB copper and thermal pad soldering per RθJB = 17.4°C/W. |
| Output Voltage Range | 0.9 V to 5.5 V adjustable - set via FB resistive divider; initial accuracy ±2.5% (780–820 mV at 0.8 V reference). |
| Switching Frequency | 2.5 MHz (FSW = Low) or 1.25 MHz (FSW = High) - selectable for trade-off between solution size (smaller inductor/capacitor) and efficiency/ripple. |
| Quiescent Current | 19 µA typical - enables >100-hour standby in battery-powered systems without compromising startup time or regulation. |
| Power Good Threshold | Rising: 92–98% of VOUT - open-drain PG pin signals valid regulation; requires external pull-up; high-impedance during EN=Low/UVLO. |
| Thermal Shutdown | 160°C with 20°C hysteresis - disables both FETs and resets soft-start; resumes regulation after cooldown with controlled ramp. |
Pinout & Package
TLV62130RGTR is housed in a 3.00 mm × 3.00 mm, 16-pin VQFN package (RGT) with exposed thermal pad soldered to AGND/PGND plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (1,2,3) | Switch node | Connects internal high-side/low-side MOSFETs to external inductor; carries high di/dt; requires short, low-inductance layout. |
| PGND (15,16) | Power ground | Return path for high-current switch node; must connect directly to exposed thermal pad and shared ground plane. |
| AGND (6) | Analog ground | Reference for feedback, control logic, and error amplifier; isolated from PGND at board level but tied at thermal pad. |
| PVIN (11,12) | Power supply input (power stage) | High-current VIN path for MOSFET drivers; decoupled with ≥10 µF ceramic near pin; separate from AVIN for noise isolation. |
| AVIN (10) | Power supply input (control circuitry) | Low-noise VIN for bias, reference, and logic; connected to same source as PVIN but routed separately to minimize coupling. |
| FB (5) | Voltage feedback input | Monitors output via resistor divider; 0.8 V internal reference; leakage <100 nA ensures accuracy with high-R dividers. |
| EN (13) | Enable input | Active-high logic; internal 400 kΩ pull-down ensures safe default-off state; enables sequencing with other rails. |
| SS/TR (9) | Soft-start / tracking | External capacitor sets output ramp rate; supports monotonic startup into pre-biased outputs and voltage tracking. |
| DEF (8) | Output voltage scaling | Low = nominal VOUT; High = VOUT + 5%; internal pull-down ensures default nominal setting if unconnected. |
| FSW (7) | Frequency select | Low = 2.5 MHz (compact design); High = 1.25 MHz (higher efficiency); internal pull-down mandates start at Low. |
| PG (4) | Power good output | Open-drain signal indicating VOUT within ±5% of target; sinks 2 mA; high-impedance during shutdown/UVLO. |
| VOS (14) | Output voltage sense | Direct connection to output for remote sensing; improves load regulation by compensating for PCB trace IR drop. |
Key Features
| Feature | Design Value |

| 100% duty cycle operation | Extends battery runtime by regulating down to VIN ≈ VOUT + IOUT × (RDS(on)HS + RL); no dropout voltage penalty. |
| Programmable soft-start | Prevents inrush current spikes during startup; supports tracking configurations using external voltage on SS/TR pin. |
| Integrated protection | Includes undervoltage lockout (2.7 V threshold), thermal shutdown (160°C), short-circuit current limiting (1.6 A pre-bias), and overcurrent foldback. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62130ARGTR | Identical pinout and electrical specs, but PG pin asserts Low (not high-impedance) during shutdown/UVLO - enables active discharge of VOUT. | Required where controlled VOUT discharge is needed for safety or sequencing; not interchangeable without verifying PG logic in system firmware. | Select TLV62130ARGTR only if active-low PG behavior is explicitly required; otherwise TLV62130RGTR is preferred for simpler sequencing. |
| TPS62130RGTR | Pin-compatible upgrade with improved features: lower RDS(on) (65/30 mΩ), higher efficiency (>95% at 1 A), and enhanced thermal performance (RθJA = 39°C/W). | Offers longer battery life and cooler operation in space-constrained designs; supports same 3–17 V input and 0.9–5.5 V output range. | Choose TPS62130RGTR for new designs demanding higher efficiency or lower thermal resistance; TLV62130RGTR remains valid for cost-sensitive legacy replacements. |
Compared with TLV62130ARGTR, TLV62130RGTR provides safer default PG behavior during fault conditions; compared with TPS62130RGTR, it trades ~3% peak efficiency and higher thermal resistance for lower unit cost and established qualification history in industrial deployments.

FAQ
What is the maximum input voltage rating for TLV62130RGTR?
The absolute maximum input voltage for TLV62130RGTR is 20 V on AVIN and PVIN pins, but the recommended operating range is 3 V to 17 V. Operation above 17 V risks exceeding thermal limits or violating safe operating area margins, especially at full 3-A load. Always observe derating curves in the datasheet's thermal information section when operating near maximum ratings.
Does TLV62130RGTR support pre-biased output startup?
Yes, TLV62130RGTR supports monotonic pre-biased startup: when enabled into a pre-charged output, the low-side MOSFET remains off until the internal soft-start ramp exceeds the existing VOUT, preventing reverse current flow. During this phase, the current limit is reduced to 1.6 A typical to protect external components and ensure controlled ramp-up.
How does the FSW pin affect TLV62130RGTR efficiency and output ripple?
When FSW = Low, TLV62130RGTR operates at ~2.5 MHz, enabling smaller inductors (e.g., 1 µH) and lower output ripple (<15 mVpp) but with higher switching losses. When FSW = High, frequency drops to ~1.25 MHz, improving peak efficiency by ~2–3% at mid-load but increasing ripple - requiring ≥2.2 µH inductor and larger output capacitance to maintain regulation.
Can TLV62130RGTR be used in 100% duty cycle mode, and what are the limitations?
Yes, TLV62130RGTR enters 100% duty cycle mode when VIN approaches VOUT, maintaining regulation down to VIN ≈ VOUT + IOUT × (RDS(on)HS + RL). At 3 A and 3.3 V output, minimum VIN is ~3.6 V. Below this, output droops; the device does not regulate - unlike LDOs, it cannot sustain regulation below its calculated dropout voltage.
What is the function of the VOS pin on TLV62130RGTR, and when should it be used?
The VOS pin on TLV62130RGTR provides remote output voltage sensing, connecting directly to the load to compensate for IR drop across PCB traces or connectors. Use VOS when load regulation error exceeds 1% due to trace resistance - tie VOS to the load-side of the output capacitor and route it with a dedicated pair away from noisy SW or PGND paths.
