Product details
Overview
TPS62150RGTT from Texas Instruments is a synchronous step-down DC-DC converter optimized for high-power-density applications. It delivers up to 1-A continuous output current, supports input voltages from 3 V to 17 V, and provides adjustable output voltage from 0.9 V to 6 V using external feedback resistors. Its DCS-Control™ topology enables fast transient response and high output-voltage accuracy in compact 3-mm × 3-mm VQFN-16 packages - ideal for POL supplies in battery-powered embedded systems and solid-state drives.
For engineers reviewing the TPS62150RGTT datasheet, TPS62150RGTT pinout, TPS62150RGTT application, or TPS62150RGTT 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 TPS62150RGTT implements DCS-Control™ topology - a hybrid regulation scheme combining voltage-mode and hysteretic control with direct AC loop feedback to the comparator stage - enabling stable operation with small ceramic capacitors and fast load-step response. Its internal compensation eliminates need for external type-II/III networks.
It operates in pulse-width modulation (PWM) mode at nominal 2.5 MHz (FSW = low) or 1.25 MHz (FSW = high), transitioning seamlessly into power-save mode at light loads via linear frequency scaling. The device supports 100% duty-cycle operation when VIN approaches VOUT, maintaining regulation down to VIN ≈ VOUT + IOUT × RDS(on)_HS + IOUT × RL.
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 powering core logic, memory, and interface ICs in embedded and mobile platforms. |
| Output Voltage Range | 0.9 V to 6 V (adjustable via FB pin) - covers common processor core, I/O, and peripheral supply requirements. |
| Quiescent Current | 17 µA (typ.) - enables >10-year battery life in always-on IoT sensors and low-power standby modes. |
| Switching Frequency | Selectable 1.25 MHz / 2.5 MHz - trade-off between efficiency (lower fSW) and solution size (higher fSW). |
| Thermal Shutdown | 160°C (typ.), 20°C hysteresis - protects against sustained overload or poor PCB thermal design without latch-up. |

Pinout & Package
TPS62150RGTT is housed in a thermally enhanced 16-pin VQFN package (RGT) measuring 3.00 mm × 3.00 mm with an exposed thermal pad. The package supports high-current routing and efficient heat dissipation when soldered to a multi-layer PCB with adequate copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2,3 SW | Switch Node | Connects to internal high-/low-side MOSFETs; requires low-inductance path to inductor and output capacitor. |
| 4 PG | Power-Good Output | Open-drain status signal indicating regulated VOUT; requires external pullup resistor (≤10 kΩ to ≤7 V). |
| 5 FB | Voltage Feedback Input | Sets output voltage via external resistor divider; referenced to AGND; must be connected for adjustable operation. |
| 6 AGND | Analog Ground | Reference for control circuitry; must connect directly to thermal pad and system ground plane. |
| 7 FSW | Frequency Select Input | Low = ~2.5 MHz, High = ~1.25 MHz; internal pulldown ensures default high-frequency operation. |
| 8 DEF | Output Voltage Scaling Input | Low = nominal VOUT, High = VOUT + 5%; enables margining without changing external components. |
| 9 SS/TR | Soft-Start / Tracking Input | Controls startup ramp time via external capacitor; also accepts external voltage for rail tracking. |
| 10 AVIN | Analog Supply Input | Powers control circuitry; tie to same source as PVIN for optimal noise immunity. |
| 11,12 PVIN | Power Stage Supply Input | High-current input for MOSFET drivers; requires local bulk and high-frequency decoupling. |
| 13 EN | Enable Input | Active-high; internal 400-kΩ pulldown ensures safe default shutdown state. |
| 14 VOS | Output Voltage Sense | Direct connection point for remote sensing or precision regulation; improves load regulation accuracy. |
| 15,16 PGND | Power Ground | Return path for high-current switching; must connect directly to thermal pad and minimize loop area. |
| Exposed Pad | Thermal & Electrical Ground | Must be soldered to AGND/PGND ground plane; critical for thermal performance and EMI reduction. |

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-16 package, 3–17 V input, but fixed 3.3-V output and 3-A rating; lacks DEF/SS/TR pins. | Best for cost-sensitive, fixed-voltage designs where output adjustability and margining are unnecessary. | Select TPS62130ARGTR only if 3.3-V fixed output suffices and higher current headroom is needed - not a drop-in replacement for TPS62150RGTT. |
| TPS62140RGTR | Pin-compatible family member with identical pinout and package, but rated for 3–6 V input and 1.2-A output; lower VIN limit restricts battery compatibility. | Suitable for low-input applications like single-cell Li-ion (3–4.2 V) or USB-powered devices where 17-V tolerance is unnecessary. | Choose TPS62140RGTR when input never exceeds 6 V and higher efficiency at ultra-low VIN is prioritized - verify UVLO (2.5 V) matches system requirements. |
Compared with TPS62130ARGTR and TPS62140RGTR, the TPS62150RGTT uniquely balances wide 3–17-V input support, adjustable output, and comprehensive feature set (DEF, SS/TR, VOS) - making it the only option among the three capable of full margining, tracking, and 100% duty-cycle operation across automotive and industrial battery ranges.

FAQ
What is the maximum output current capability of the TPS62150RGTT?
The TPS62150RGTT delivers up to 1 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Peak current capability reaches ~1.7 A before current-limit activation, but sustained operation above 1 A requires careful thermal management and may trigger thermal shutdown depending on ambient conditions and layout.
Does the TPS62150RGTT support output voltage margining, and how is it implemented?
Yes, the TPS62150RGTT supports output voltage margining via the DEF pin: pulling DEF low sets nominal output voltage, while pulling DEF high increases output by +5%. This allows real-time validation of system voltage tolerance margins without changing external feedback resistors - a key feature confirmed in the device's electrical characteristics table and functional description.
Can the TPS62150RGTT operate with input voltage close to the output voltage, and what mechanism enables this?
Yes, the TPS62150RGTT supports 100% duty-cycle operation when input voltage approaches output voltage - maintaining regulation down to VIN ≈ VOUT + IOUT × (RDS(on)_HS + RL). This is enabled by turning on the high-side MOSFET continuously while disabling the low-side switch, extending usable battery range in portable applications.
What is the purpose of the VOS pin on the TPS62150RGTT, and when should it be used?
The VOS (Voltage Output Sense) pin on the TPS62150RGTT provides a dedicated Kelvin connection point for remote output voltage sensing, improving load regulation accuracy by compensating for PCB trace resistance. It should be used in high-precision applications or when output current exceeds 500 mA and trace IR drop exceeds 10 mV - connecting VOS directly to the load side of the output capacitor.
How does the TPS62150RGTT handle power sequencing in multi-rail systems?
The TPS62150RGTT supports power sequencing through coordinated use of its EN (enable) and PG (power-good) pins: EN can be driven by another rail's PG signal to enforce startup order, while its own open-drain PG output indicates valid VOUT to downstream controllers. This enables reliable, hardware-based sequencing without external supervisors - verified in typical application schematics and timing diagrams.
