Product details
Overview
TPS62150ARGTR from Texas Instruments is a synchronous step-down DC-DC converter optimized for high-power-density applications, delivering up to 1-A continuous output current across an input range of 3 V to 17 V, with adjustable output voltage from 0.9 V to 6 V, and featuring DCS-Control™ topology for fast transient response-used in solid-state drives and embedded systems requiring compact, efficient POL regulation.
For engineers reviewing the TPS62150ARGTR datasheet, TPS62150ARGTR pinout, TPS62150ARGTR application, or TPS62150ARGTR equivalent, key selection criteria include its 2.5-MHz nominal switching frequency, 17-µA quiescent current in power-save mode, 100% duty-cycle capability for battery-end-of-life operation, and seamless PWM-to-power-save transition without output disturbance.
Technical Context
The TPS62150ARGTR implements DCS-Control™ topology-a hybrid regulation scheme combining voltage-mode stability, current-mode responsiveness, and hysteretic loop dynamics-enabling direct ac feedback from the output node to a fast comparator while maintaining precise dc load regulation via an internally compensated error amplifier. This architecture supports both continuous-conduction mode (CCM) at 2.5 MHz (FSW = low) and variable-frequency power-save mode at light loads.
It integrates dual MOSFET power switches with typical RDS(on) of 90 mΩ (high-side, VIN ≥ 6 V) and 40 mΩ (low-side, VIN ≥ 6 V), enabling high efficiency across 3–17-V inputs and supporting 100% duty-cycle operation when VIN approaches VOUT-critical for Li-ion battery discharge tail-end regulation. Protection includes thermal shutdown at 160°C, undervoltage lockout at 2.7 V (200-mV hysteresis), and short-circuit current limiting with dynamic peak threshold of 1.7 A.
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 1 A continuous - sufficient for core logic, memory, and I/O rails in embedded and mobile computing platforms. |
| Switching Frequency | 2.5 MHz (typ., FSW = low) or 1.25 MHz (FSW = high) - enables use of ≤2.2-µH inductors and 22-µF ceramic output capacitors for ultra-compact layouts. |
| Quiescent Current | 17 µA (typ.) in power-save mode - extends battery runtime in always-on or low-duty-cycle IoT and portable devices. |
| Output Voltage Range | 0.9 V to 6 V (adjustable via FB divider) - covers DDR termination, FPGA core, MCU I/O, and analog subsystems. |
| Power-Good Output | Open-drain PG with 92–98% rising threshold - enables reliable power sequencing and system reset assertion in multi-rail designs. |
| Thermal Shutdown | 160°C junction temperature with 20°C hysteresis - ensures safe operation under sustained overload or poor PCB thermal design. |
Pinout & Package
TPS62150ARGTR is housed in a thermally enhanced 3-mm × 3-mm VQFN-16 package (RGT) with exposed thermal pad, requiring solder connection to AGND/PGND plane for optimal thermal performance (RθJA = 45°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2,3 SW | Switch Node | Connection point for external inductor; carries high di/dt switching current-requires short, low-inductance routing to minimize EMI and voltage spikes. |
| 4 PG | Power-Good Output | Open-drain status signal indicating regulated output; requires external pullup resistor (≤100 kΩ) to voltage ≤7 V for proper logic-level interpretation. |
| 5 FB | Feedback Input | Sense point for adjustable output voltage; connects to resistive divider from VOUT-accuracy depends on resistor tolerance and layout symmetry. |
| 6 AGND | Analog Ground | Reference for control circuitry; must be tied directly to exposed thermal pad and common ground plane to minimize noise coupling into error amplifier. |
| 7 FSW | Frequency Select | Logic input selecting 2.5 MHz (low) or 1.25 MHz (high); internal pulldown ensures default high-frequency operation if left unconnected. |
| 8 DEF | Output Voltage Scaling | Logic input adding +5% to nominal VOUT when high; enables margin testing and adaptive voltage scaling without hardware change. |
| 9 SS/TR | Soft-Start / Tracking | Capacitor-controlled ramp generator for monotonic startup or master-slave voltage tracking; supports pre-biased output conditions. |
| 10 AVIN | Analog Supply | Provides bias for control circuitry; must be connected to same source as PVIN to avoid supply mismatch and instability. |
| 11,12 PVIN | Power Supply Input | High-current input for power stage; requires local 10-µF ceramic capacitor near pins 11/12 to suppress high-frequency ripple. |
| 13 EN | Enable Input | Active-high logic control; internal 400-kΩ pulldown ensures safe disable on power-up; used for rail sequencing and standby mode entry. |
| 14 VOS | Voltage Sense | Direct connection to output for improved regulation accuracy and load-transient response; bypassed in fixed-output variants. |
| 15,16 PGND | Power Ground | Return path for high-current switching loops; must be tied to exposed thermal pad and separated from AGND at single-point star ground. |
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 |
|---|---|---|---|
| TPS62130ARGTR | Same 3×3-mm QFN package and pinout; lower 3–6-V input range and 3-A output current rating. | Better suited for higher-current, lower-input applications like USB-C PD sink rails-not compatible with 12-V or 17-V inputs. | Select TPS62130ARGTR only if input voltage never exceeds 6 V and load current exceeds 1 A. |
| TPS62140ARGTR | Identical 3–17-V input and 1-A rating; differs in PG logic (active-low vs. high-impedance) and soft-start behavior. | Requires redesign of PG pullup network and sequencing logic if replacing TPS62150ARGTR in existing systems. | Choose TPS62140ARGTR when active-low PG is needed for direct microcontroller interrupt triggering without external logic. |
Compared with TPS62130ARGTR and TPS62140ARGTR, the TPS62150ARGTR uniquely balances wide-input operation (3–17 V), 1-A capability, and high-frequency DCS-Control™ performance-making it the preferred choice for multi-source power systems where input flexibility and transient robustness are critical.

FAQ
What is the maximum output current supported by the TPS62150ARGTR?
The TPS62150ARGTR supports up to 1 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, proper thermal layout). Peak current capability reaches 1.7 A before current-limit activation, but sustained operation above 1 A requires careful thermal design due to RDS(on) losses and ambient constraints. Derating is advised above 85°C ambient.
Does the TPS62150ARGTR support 100% duty-cycle operation, and what is its minimum input voltage for regulation?
Yes, the TPS62150ARGTR enters 100% duty-cycle mode automatically when VIN approaches VOUT, maintaining regulation down to VIN ≈ VOUT + IOUT × (RDS(on) + RL). For example, at 1 A and 1.8 V output, minimum VIN is ~2.05 V (using typical 90-mΩ high-side RDS(on) and 20-mΩ inductor DCR). This extends battery runtime in single-cell Li-ion systems.
How does the DCS-Control™ topology in the TPS62150ARGTR improve transient response compared to conventional voltage-mode control?
The DCS-Control™ topology in the TPS62150ARGTR embeds an ac path directly from the output node to a high-speed comparator, enabling sub-microsecond detection of output voltage deviations. Combined with a stable dc feedback loop, this achieves <5-µs load transient recovery with minimal overshoot-superior to traditional voltage-mode controllers that rely solely on slower error-amplifier bandwidth.
Can the TPS62150ARGTR be used with a pre-biased output, and how does soft-start behave in that condition?
Yes, the TPS62150ARGTR supports monotonic start-up into a pre-biased output. When EN is asserted, the internal soft-start ramp begins only after detecting that VOUT is below the target; both MOSFETs remain off until the ramp exceeds the pre-bias level. This prevents reverse current flow and ensures controlled voltage rise without external circuitry.
What is the function of the VOS pin on the TPS62150ARGTR, and is it required for basic operation?
The VOS pin on the TPS62150ARGTR provides direct output voltage sensing for the control loop, improving regulation accuracy and load-transient response. It is not required for basic operation-the device functions correctly with only FB connected-but connecting VOS to VOUT reduces output impedance effects and enhances stability under dynamic loads, especially with long PCB traces.
