Product details
Overview
TPS62130ARGTT from Texas Instruments is an adjustable-output, 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, regulates output voltage from 0.9 V to 6 V via external feedback divider, and features DCS-Control™ topology for fast transient response and seamless PWM-to-power-save mode transition - used in solid-state drives and embedded systems requiring compact, efficient 12-V rail conversion.
For engineers reviewing the TPS62130ARGTT datasheet, TPS62130ARGTT pinout, TPS62130ARGTT application, or TPS62130ARGTT equivalent, key selection criteria include its 2.5 MHz (or 1.25 MHz) selectable switching frequency, 17 µA typical quiescent current in power save mode, 100% duty cycle capability for low-dropout operation, and integrated power-good open-drain output with ±5% output voltage margining via DEF pin.
Technical Context
The TPS62130ARGTT implements DCS-Control™ - a hybrid regulation topology combining voltage-mode and hysteretic control with direct AC feedback from the output node to a fast comparator, enabling stable regulation with small ceramic capacitors and minimal external components. Its internal error amplifier and compensated network ensure <±1% DC load regulation across –40°C to 125°C junction temperature.
It supports dual functional modes: fixed-frequency PWM (2.5 MHz typical, FSW = Low) for heavy loads and variable-frequency power save mode (frequency scales linearly with load) for light-load efficiency. The device enters 100% duty cycle mode when VIN approaches VOUT, maintaining regulation down to VIN ≈ VOUT + IOUT × (RDS(on)_HS + RL) - critical for Li-ion battery discharge tail-end operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports single/multi-cell Li-ion batteries and standard 12-V intermediate rails without external pre-regulation. |
| Output Current | Up to 3 A continuous - enables replacement of discrete buck controllers + MOSFETs in space-constrained POL designs. |
| Output Voltage Range | 0.9 V to 6 V (adjustable via FB pin) - covers core logic, I/O, and memory supply requirements across embedded and computing platforms. |
| Switching Frequency | 1.25 MHz or 2.5 MHz (pin-selectable via FSW) - balances efficiency vs. solution size: 2.5 MHz allows ≤1 µH inductors; 1.25 MHz improves light-load efficiency. |
| Quiescent Current | 17 µA typical (power save mode) - extends battery runtime in always-on subsystems like modem standby or sensor wake-up circuits. |
| Power-Good Output | Open-drain PG with 92–98% VOUT threshold - provides reliable sequencing signal for multi-rail systems without external monitoring ICs. |
| Thermal Protection | 160°C shutdown with 20°C hysteresis - prevents thermal runaway during sustained overload or poor PCB heatsinking. |
Pinout & Package
TPS62130ARGTT is housed in a thermally enhanced 3 mm × 3 mm, 16-pin VQFN package (RGT) with exposed thermal pad soldered to AGND/PGND for optimal power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN (1,2,3,11,12) | Power input for high-current path | Connects directly to input capacitor and inductor; multiple pins reduce trace resistance and improve thermal performance. |
| SW (1,2,3) | Switch node | Drives external inductor; requires low-inductance layout to minimize EMI and switching losses. |
| PG (4) | Open-drain power-good indicator | Signals VOUT regulation status; requires external pullup resistor (typically to VOUT or 3.3 V). |
| FB (5) | Feedback input for adjustable output | Sets output voltage via resistive divider; connects to AGND on fixed-output variants to improve thermal stability. |
| AGND (6) | Analog ground reference | Must be tied directly to exposed thermal pad and system ground plane to maintain control-loop accuracy. |
| FSW (7) | Frequency select input | Low = ~2.5 MHz (smaller magnetics); High = ~1.25 MHz (higher light-load efficiency); internal pulldown ensures safe default. |
| DEF (8) | Output voltage scaling input | Low = nominal VOUT; High = VOUT +5%; enables hardware-based voltage margining for system validation. |
| SS/TR (9) | Soft-start/tracking control | External capacitor sets startup ramp time; also accepts external voltage for supply tracking in multi-rail sequencing. |
| AVIN (10) | Analog supply input | Must tie to same source as PVIN; powers internal control circuitry independently from power stage. |
| EN (13) | Enable input | Active-high logic; internal 400 kΩ pulldown ensures safe shutdown if left floating. |
| VOS (14) | Output voltage sense | Provides precise sensing point for control loop; improves regulation accuracy under high-current PCB trace resistance. |
| PGND (15,16) | Power ground return | High-current return path for power stage; must connect directly to exposed thermal pad and ground plane. |

The TPS62130ARGTT delivers up to 3 A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Peak current limit is typically 4.2 A, but sustained operation above 3 A requires careful thermal management using the exposed thermal pad and adequate copper area per TI's layout guidelines.
Does the TPS62130ARGTT support output voltage adjustment, and how is it configured?
Yes, the TPS62130ARGTT is an adjustable-output converter. Output voltage is set via an external resistive divider connected between VOUT, FB, and AGND. The FB pin references 0.8 V internally; VOUT = 0.8 V × (1 + R1/R2). For fixed-output alternatives, TI offers pin-compatible variants like TPS62132ARGTT (3.3 V) and TPS62133ARGTT (5.0 V).
How does the DCS-Control™ topology in the TPS62130ARGTT improve transient response?
The DCS-Control™ topology in the TPS62130ARGTT uses direct AC feedback from the output node to a high-speed comparator, enabling sub-microsecond response to load steps. This architecture maintains tight regulation (<±10 mV deviation) during 1-A load transients without requiring large output capacitance - critical for powering noise-sensitive RF and high-speed digital circuits.
Can the TPS62130ARGTT operate with input voltage close to the output voltage?
Yes, the TPS62130ARGTT supports 100% duty cycle operation, allowing regulation when input voltage drops near the output level - for example, sustaining 3.3 V output from a discharging 3.6-V Li-ion cell. In this mode, the high-side MOSFET remains continuously on, minimizing dropout voltage and maximizing battery utilization.
What protection features are integrated into the TPS62130ARGTT?
The TPS62130ARGTT integrates undervoltage lockout (2.7 V threshold), overtemperature shutdown (160°C), short-circuit protection (1.6 A fault current limit), and shoot-through prevention.
