Product details
Overview
TPS62150AQRGTRQ1 from Texas Instruments is an AEC-Q100 qualified 3-V to 17-V, 1-A synchronous step-down DC-DC converter with DCS-Control™ topology, adjustable 0.9 V–6 V output, 2.5 MHz (or 1.25 MHz) switching frequency, and 17 µA quiescent current - used in automotive ADAS camera power rails.
For engineers reviewing the TPS62150AQRGTRQ1 datasheet, TPS62150AQRGTRQ1 pinout, TPS62150AQRGTRQ1 application, or TPS62150AQRGTRQ1 equivalent, key selection criteria include automotive-grade thermal performance (–40°C to 125°C TJ), seamless PWM-to-Power Save Mode transition, pin-selectable +5% voltage margining, and open-drain power good signaling for rail sequencing.
Technical Context
The TPS62150AQRGTRQ1 implements DCS-Control™ - a hybrid regulation architecture combining fast AC response via direct output-voltage sensing with stable DC regulation through an internal error amplifier and compensated feedback loop. It supports both continuous conduction mode (CCM) at full load and discontinuous conduction mode (DCM) during light-load Power Save Mode, with seamless mode transitions.
Its control logic integrates undervoltage lockout (2.7 V threshold), thermal shutdown (160°C), 100% duty-cycle operation for near-input-output voltage conditions, and programmable soft-start/tracking via external capacitor on SS/TR. The FSW and DEF pins enable runtime configuration of switching frequency and output voltage scaling without reprogramming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports wide automotive bus rails including 12 V and 24 V systems with transient tolerance. |
| Output Current | 1 A continuous - delivers full rated current across full temperature range with proper thermal layout. |
| Switching Frequency | 2.5 MHz (FSW = Low) or 1.25 MHz (FSW = High) - enables compact 2.2 µH inductor and 22 µF output capacitor design. |
| Quiescent Current | 17 µA typical - sustains ultra-low standby power in always-on automotive modules like camera ECU. |
| Output Voltage Range | 0.9 V to 6 V adjustable - set via external resistor divider on FB pin; supports core, I/O, and interface rail requirements. |
| Power Good Output | Open-drain PG with 92–98% rising threshold - provides reliable system-level power sequencing and fault indication. |
| Thermal Rating | –40°C to +125°C junction temperature - qualified per AEC-Q100 Grade 1 for under-hood and cabin applications. |
Pinout & Package
TPS62150AQRGTRQ1 is housed in a thermally enhanced 3 mm × 3 mm VQFN-16 package (RGT) with exposed thermal pad soldered to AGND/PGND for optimal power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (Pins 1,2,3) | Switch node | Connects internal high- and low-side MOSFETs to external inductor; requires low-inductance layout to minimize EMI. |
| PG (Pin 4) | Power good indicator | Open-drain output signaling valid VOUT; requires external pullup to ≤7 V (e.g., VOUT) for sequencing. |
| FB (Pin 5) | Voltage feedback input | Sets output voltage via resistive divider; referenced to AGND; accuracy ±1.8% in PWM mode. |
| AGND (Pin 6) | Analog ground | Reference for control circuitry; must connect directly to exposed thermal pad and system ground plane. |
| FSW (Pin 7) | Frequency select input | Low = 2.5 MHz, High = 1.25 MHz; internal 400 kΩ pulldown ensures default high-frequency operation. |
| DEF (Pin 8) | Output voltage scaling | Low = nominal VOUT, High = VOUT +5%; enables dynamic voltage margining for SoC testing or aging compensation. |
| SS/TR (Pin 9) | Soft-start / tracking | External capacitor sets startup ramp time; also accepts external voltage for supply tracking in multi-rail systems. |
| AVIN (Pin 10) | Analog supply | Bias for control circuitry; tie to same source as PVIN for noise isolation and stable reference. |
| PVIN (Pins 11,12) | Power stage supply | High-current input for MOSFET drivers; use separate low-ESR input capacitors near these pins. |
| EN (Pin 13) | Enable input | Active-high logic; threshold ~0.65 V rising; internal pulldown allows default disable if left floating. |
| VOS (Pin 14) | Output voltage sense | Direct connection to output rail for precise remote sensing; improves regulation under PCB trace resistance. |
| PGND (Pins 15,16) | Power ground | Return path for high-current switch node; must connect to exposed thermal pad and minimize loop area. |
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 |
|---|---|---|---|
| TPS62130AQRGTRQ1 | Same 3–17 V input, 1 A, VQFN-16 package, but fixed 3.3 V output; lacks DEF and VOS pins. | No voltage margining or remote sensing; suitable only for fixed-rail applications without sequencing or precision feedback needs. | Select when board space and BOM count must be minimized and output voltage is invariant. |
| LM61480QRNRRQ1 | Higher 3.5 A rating, 2.1 MHz fixed frequency, lower 15 µA IQ, but larger 16-pin WQFN package (4 × 4 mm). | Better suited for multi-rail systems requiring higher current headroom or tighter output voltage accuracy (±0.5%). | Choose when future scalability to >1 A loads or tighter regulation tolerance is required. |
Compared with TPS62150AQRGTRQ1, TPS62130AQRGTRQ1 offers identical footprint and thermal performance but sacrifices adjustability and diagnostics, while LM61480QRNRRQ1 trades size and cost for higher current capability and improved accuracy - making TPS62150AQRGTRQ1 optimal for compact, flexible 1-A automotive PoL designs.

FAQ
What is the maximum output current capability of the TPS62150AQRGTRQ1 under automotive operating conditions?
The TPS62150AQRGTRQ1 delivers 1 A continuous output current across its full operating junction temperature range of –40°C to +125°C, provided the PCB layout includes adequate copper area on the exposed thermal pad and PGND/AGND planes. At 125°C TJ, derating is not required due to its robust thermal design (RθJA = 45°C/W) and integrated overtemperature protection that activates at 160°C.
How does the DCS-Control™ topology in the TPS62150AQRGTRQ1 improve transient response compared to conventional voltage-mode controllers?
The TPS62150AQRGTRQ1 uses DCS-Control™ to directly sense output voltage changes via a fast comparator, enabling sub-microsecond response to load steps without relying on slow error amplifier loops. This results in <50 mV output deviation during 100 mA–1 A transients at 2.5 MHz switching - significantly tighter than typical voltage-mode controllers - while maintaining stability with low-ESR ceramic capacitors and no external compensation.
Can the TPS62150AQRGTRQ1 operate with an input voltage as low as 3.3 V while regulating a 3.3 V output?
Yes - the TPS62150AQRGTRQ1 supports 100% duty-cycle operation, allowing it to maintain regulation when VIN drops to within ~15% above VOUT (e.g., 3.3 V output with 3.8 V input). At exactly 3.3 V input, the device sustains output by holding the high-side FET fully on and disabling the low-side FET, making it ideal for battery-cranking scenarios in automotive start-stop systems.
What is the purpose of the VOS pin on the TPS62150AQRGTRQ1, and how should it be connected?
The VOS (Voltage Output Sense) pin on the TPS62150AQRGTRQ1 provides Kelvin sensing of the output voltage at the load, compensating for IR drop across PCB traces. It must be connected directly to the output capacitor's positive terminal or the load's power input node - never to the SW or FB nodes. When used, it improves load regulation accuracy to ±0.5% across varying current levels, critical for precision SoC or sensor rails.
Is the TPS62150AQRGTRQ1 pin-compatible with other members of the TPS6215x-Q1 family, and what are the key functional differences?
Yes - the TPS62150AQRGTRQ1 shares identical VQFN-16 (RGT) pinout and footprint with TPS62152AQRGTRQ1 (3.3 V fixed) and TPS62153AQRGTRQ1 (5 V fixed). Key differences include: TPS62150AQRGTRQ1 supports adjustable output via FB divider and includes VOS/DEF pins; fixed-output variants omit those pins and hardwire FB internally. All share identical thermal, electrical, and automotive qualification specs.
