Product details
Overview
TPS62150RGTRF0 from Texas Instruments is an adjustable-output, synchronous step-down DC-DC converter optimized for high-power-density applications. It operates from 3 V to 17 V input, delivers up to 1 A continuous output current, regulates output voltage from 0.9 V to 6 V via external feedback resistors, and features DCS-Control™ topology for fast transient response-used in solid-state drives and embedded systems requiring compact, efficient POL conversion.
For engineers reviewing the TPS62150RGTRF0 datasheet, TPS62150RGTRF0 pinout, TPS62150RGTRF0 application, or TPS62150RGTRF0 equivalent, key selection criteria include its 2.5 MHz (or 1.25 MHz) selectable switching frequency, 17 µA quiescent current in power-save mode, seamless PWM-to-PSM transition, 100% duty-cycle capability for low-dropout operation, and integrated power-good and thermal/short-circuit protection.
Technical Context
The TPS62150RGTRF0 implements DCS-Control™ topology-a hybrid regulation scheme combining voltage-mode stability with hysteretic-like transient response-enabling direct ac loop control of output voltage and fast load-step recovery without external compensation. Its internal error amplifier and comparator-driven timing circuitry maintain ±1.5% initial output voltage accuracy at the FB pin and support monotonic start-up into pre-biased outputs.
It supports three functional modes: continuous-conduction PWM (2.5 MHz typical), discontinuous-conduction power-save mode (frequency scales linearly with load), and 100% duty-cycle operation below ~1.15×VOUT-enabled by adaptive on-time control and internal high-side MOSFET gate drive. Protection includes undervoltage lockout (2.7 V threshold, 200 mV hysteresis), thermal shutdown (160°C, 20°C hysteresis), and cycle-by-cycle current limiting (1.7 A typical high-side limit).
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 LDO pre-regulation. |
| Output Current | Up to 1 A continuous - sufficient for core logic rails in mobile PCs, SSDs, and microservers. |
| Output Voltage Range | 0.9 V to 6 V adjustable - set via external resistor divider on FB pin; enables precise core voltage tuning for ASICs/FPGAs. |
| Quiescent Current | 17 µA (typ.) - maintains high light-load efficiency in always-on subsystems without compromising standby battery life. |
| Switching Frequency | Selectable: 2.5 MHz (FSW = low) or 1.25 MHz (FSW = high) - trade-off between small inductor size (2.2 µH min at 1.25 MHz) and lower switching loss. |
| Power-Good Output | Open-drain PG with 95% rising threshold - provides reliable rail sequencing signal for multi-rail systems; requires external pullup. |
| Thermal Shutdown | 160°C junction temperature with 20°C hysteresis - protects against sustained overload or poor PCB thermal design without latch-up. |
Pinout & Package
TPS62150RGTRF0 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 and EMI performance.
| 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 layout to minimize ringing. |
| 4 PG | Power-good open-drain output | Indicates regulated output; high-impedance when enabled and VOUT ≥ 95% nominal-used for system reset or enable sequencing. |
| 5 FB | Feedback input | Senses output voltage via resistor divider; sets regulation point for adjustable versions-must be connected to AGND on fixed-output variants. |
| 6 AGND | Analog ground | Reference for control circuitry; must tie directly to exposed thermal pad and system ground plane to avoid noise coupling. |
| 7 FSW | Frequency select input | Low = 2.5 MHz (high density), high = 1.25 MHz (higher efficiency); internal pulldown ensures default high-frequency operation. |
| 8 DEF | Output voltage scaling input | Low = nominal VOUT, high = VOUT + 5%-enables dynamic voltage margining for system validation or aging compensation. |
| 9 SS/TR | Soft-start/tracking input | External capacitor sets output ramp rate; also accepts external voltage for supply tracking-prevents inrush and enables monotonic start-up. |
| 10 AVIN | Analog supply input | Provides bias for control circuitry; connect to same source as PVIN but decoupled separately for noise isolation. |
| 11,12 PVIN | Power stage supply input | High-current path for MOSFET drivers; requires low-ESR bulk capacitance near pins to suppress voltage droop during switching. |
| 13 EN | Enable input | Active-high logic; internal 400-kΩ pulldown ensures safe default disable-supports power-rail sequencing when driven by another regulator's PG. |
| 14 VOS | Output voltage sense | Direct connection to output for improved loop stability and accuracy-bypasses FB divider parasitics in precision applications. |
| 15,16 PGND | Power ground | Return path for high-current switch node; must connect to exposed thermal pad and common ground to minimize ground bounce. |
| Exposed Pad | Thermal & ground reference | Electrically tied to AGND and PGND; mandatory soldering required for thermal reliability and EMI reduction per TI layout guidelines. |

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 VQFN package, 3–17-V input, but fixed 3.3-V output and no DEF/FSW pins; 1.2-MHz fixed frequency. | Lacks adjustable output and voltage margining-suitable only for static 3.3-V rail designs without sequencing or tracking needs. | Choose when output voltage is fixed and board space is constrained; not drop-in compatible due to missing FB/DEF/FSW functionality. |
| TPS62140ARGTR | Same pinout and package as TPS62150RGTRF0, but rated for 3–6-V input (not 17 V); 2.5-MHz fixed frequency; no 100% duty-cycle mode. | Cannot support 12-V input rails or deep battery discharge-limited to USB-powered or low-voltage embedded applications. | Select only for sub-6-V systems requiring identical layout; incompatible with 12-V or multi-cell battery inputs. |
Compared with TPS62130ARGTR and TPS62140ARGTR, the TPS62150RGTRF0 uniquely supports wide-input operation (up to 17 V), fully adjustable output, programmable frequency, and 100% duty-cycle mode-making it the only option among the three for scalable, battery-backed, or high-density POL designs requiring flexibility and extended input range.

FAQ
What is the maximum input voltage rating for the TPS62150RGTRF0?
The TPS62150RGTRF0 has an absolute maximum input voltage rating of 20 V on AVIN and PVIN pins, but its recommended operating input voltage range is 3 V to 17 V. Operation above 17 V may compromise long-term reliability or violate thermal limits under full load. The device includes undervoltage lockout (UVLO) that disables operation below 2.6 V to prevent unstable regulation.
Does the TPS62150RGTRF0 support power sequencing with other voltage rails?
Yes, the TPS62150RGTRF0 supports robust power sequencing via its EN and PG pins. The EN pin can be driven by another regulator's PG output to enforce turn-on order, while its own open-drain PG pin signals valid output voltage (95% of nominal) and can drive downstream EN inputs. Combined with SS/TR pin tracking, this enables precise multi-rail startup and shutdown coordination in complex systems.
Can the TPS62150RGTRF0 operate with zero output load?
Yes, the TPS62150RGTRF0 operates stably with zero output load using its automatic power-save mode. At light loads, it seamlessly transitions from PWM to PSM, reducing switching frequency and quiescent current to 17 µA (typ.), maintaining regulation without oscillation or dropout. No minimum load is required-unlike many older buck converters-making it ideal for always-on standby circuits.
What is the purpose of the VOS pin on the TPS62150RGTRF0?
The VOS (voltage output sense) pin on the TPS62150RGTRF0 provides a dedicated Kelvin connection to the output rail, bypassing PCB trace resistance and improving regulation accuracy-especially under high-current or high-temperature conditions. When used, it enhances load regulation to ±0.05%/A and reduces sensitivity to layout-induced voltage drops, making it valuable for precision applications like FPGA core supplies.
Is the TPS62150RGTRF0 pin-compatible with the TPS62151 or TPS62152?
No, the TPS62150RGTRF0 is not pin-compatible with the TPS62151 or TPS62152. While all share the same 16-pin VQFN (RGT) package and pinout, the TPS62151 (1.8 V fixed) and TPS62152 (3.3 V fixed) lack the FB pin and instead route AGND to pin 5. The TPS62150RGTRF0 requires FB for adjustable operation and uses pin 5 for feedback-making direct substitution electrically invalid without PCB redesign.
