Product details
Overview
TPS628130AQWRWYRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous step-down DC/DC converter delivering 3 A continuous output current with fixed 1.2 V output, 2.75 V to 6 V input range, ±1% output voltage accuracy in PWM mode, and adjustable switching frequency from 1.8 MHz to 4 MHz. It operates in forced PWM or PFM/PWM hybrid mode and supports precise enable sequencing and active output discharge for infotainment power rails.
For engineers reviewing the TPS628130AQWRWYRQ1 datasheet, TPS628130AQWRWYRQ1 pinout, TPS628130AQWRWYRQ1 application, or TPS628130AQWRWYRQ1 equivalent, key selection criteria include its 3 A rated current, fixed 1.2 V output, wettable-flank VQFN-9 package, AEC-Q100 qualification, and functional safety documentation support - all critical for automotive ADAS and cluster power design.
Technical Context
The TPS628130AQWRWYRQ1 implements peak current mode control with internally compensated loop architecture, supporting three selectable compensation settings via resistor on COMP/FSET to match output capacitance (27–470 µF). Its MODE/SYNC pin enables external clock synchronization (1.8–4 MHz) or forced PWM operation, while SS/TR provides programmable soft-start and voltage tracking capability.
It integrates low-RDS(on) high-side (37–60 mΩ) and low-side (15–35 mΩ) MOSFETs optimized for high ambient temperature operation, with 100% duty cycle mode, power-good window comparator, and spread spectrum clocking option - all designed to meet stringent EMI and thermal requirements in automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 3 A continuous - supports high-power SoC cores and DDR memory rails in automotive head units and ADAS sensors. |
| Output Voltage | Fixed 1.2 V ±1% (PWM) - eliminates external feedback resistors, reduces BOM count, and ensures stable core supply for processors. |
| Input Voltage Range | 2.75 V to 6 V - compatible with 3.3 V, 5 V, and battery-backed automotive supplies including cold-crank conditions down to 2.75 V. |
| Switching Frequency | 1.8 MHz to 4 MHz (adjustable) - enables compact magnetics and avoids AM radio band; supports external sync for multi-rail EMI reduction. |
| Quiescent Current | 15 µA typical - extends battery life in always-on telematics modules during vehicle sleep mode. |
| Operating Junction Temp | –40°C to +150°C - meets AEC-Q100 Grade 1 requirements for under-hood and dashboard-mounted electronics. |
| Package | VQFN-9 (RWY), 3.0 mm × 2.0 mm with wettable flanks - supports automated optical inspection (AOI) and improves solder joint reliability in automotive reflow profiles. |
Pinout & Package
VQFN-9 (RWY) package, 3.0 mm × 2.0 mm body size, 0.4 mm pitch, wettable flanks for enhanced solder inspection and mechanical robustness in automotive thermal cycling environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 8) | Enable input | Logic-controlled startup with 1.1 V rising threshold; supports external RC delay and undervoltage lockout via resistor divider. |
| FB (Pin 5) | Feedback input | Internally tied to 1.2 V reference - no external resistor divider required; simplifies layout and improves noise immunity. |
| GND (Pin 4) | Power ground | Primary return path for high-current switching loop; must be connected to low-impedance PCB ground plane beneath IC. |
| MODE/SYNC (Pin 1) | Mode control / sync input | Pull low for PFM/PWM auto-mode; pull high for forced PWM; accepts external 1.8–4 MHz clock for synchronized multi-converter systems. |
| COMP/FSET (Pin 7) | Compensation / frequency set | Resistor to GND sets both switching frequency and internal compensation network - critical for stability with chosen output capacitance. |
| PG (Pin 9) | Power-good open-drain output | Window comparator monitors regulated output; asserts high-Z when VOUT is within ±5% of 1.2 V - used for system power sequencing. |
| SS/TR (Pin 6) | Soft-start / tracking input | Capacitor to GND sets ramp time; also accepts external voltage for rail tracking - enables controlled power-up of multiple supplies. |
| SW (Pin 3) | Switch node | Connection point to external inductor; carries high di/dt pulsed current - requires short, wide copper trace and local high-frequency decoupling. |
| VIN (Pin 2) | Input supply | Accepts 2.75–6 V; requires low-ESR ceramic input capacitor (≥10 µF) placed adjacent to VIN and GND pins to suppress ripple and transients. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - ensures reliability in automotive cabin and engine-bay applications. |
| Active output discharge | Integrated 50 Ω discharge path - rapidly discharges output capacitor during shutdown, preventing unintended wake-up or latch-up in downstream logic. |
| 100% duty cycle mode | Enables dropout operation at ultra-low input voltages (e.g., 1.25 VIN → 1.2 VOUT) - critical for battery-backed backup rails during cold-crank. |
| Functional safety documentation | FIT rate, FMEA reports, and safety analysis files available - accelerates ISO 26262 ASIL-B system-level certification for ADAS power domains. |
| Spread spectrum clocking (SSC) | Optional modulation reduces peak EMI by >10 dB - helps meet CISPR 25 Class 5 radiated emissions limits without added shielding or filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS628132AQWRWYRQ1 | Fixed 1.2 V output, same 3 A rating and RWY package, but includes spread spectrum clocking enabled by default. | Preferred where CISPR 25 Class 5 EMI compliance is mandatory without external filtering. | Select TPS628132AQWRWYRQ1 if EMI reduction is prioritized over minimal quiescent current; otherwise retain TPS628130AQWRWYRQ1 for lowest IQ. |
| TPS628120AQWRWYRQ1 | 2 A rated, fixed 1.2 V output, identical pinout and feature set except lower current capability and reduced RDS(on). | Suitable for lower-power clusters or gateway MCUs where 2 A suffices and thermal margin is constrained. | Choose TPS628120AQWRWYRQ1 only when peak load remains ≤2 A; verify thermal performance with RθJA = 71.1°C/W and derating curves. |
Compared with TPS628132AQWRWYRQ1 and TPS628120AQWRWYRQ1, the TPS628130AQWRWYRQ1 offers optimal balance of 3 A capability, minimal 15 µA quiescent current, and absence of mandatory SSC - making it ideal for thermally constrained, always-on automotive subsystems requiring predictable efficiency and timing behavior.

FAQ
What is the output voltage of the TPS628130AQWRWYRQ1?
The TPS628130AQWRWYRQ1 provides a fixed 1.2 V output voltage with ±1% accuracy in PWM mode across –40°C to +125°C ambient temperature. This eliminates the need for external feedback resistors and ensures consistent core supply for automotive processors and FPGAs without calibration overhead.
Does the TPS628130AQWRWYRQ1 support external clock synchronization?
Yes, the TPS628130AQWRWYRQ1 supports external clock synchronization via its MODE/SYNC pin, accepting input frequencies from 1.8 MHz to 4 MHz. Synchronization requires a resistor from COMP/FSET to GND; tying COMP/FSET directly to GND or VIN disables sync capability while fixing frequency at 2.25 MHz.
What package type does the TPS628130AQWRWYRQ1 use?
The TPS628130AQWRWYRQ1 uses the RWY package: a 3.0 mm × 2.0 mm VQFN with 9 terminals and wettable flanks. This package enables automated optical inspection of solder joints and meets IPC-A-610 Class 3 requirements for automotive production reliability.
Is the TPS628130AQWRWYRQ1 qualified for automotive applications?
Yes, the TPS628130AQWRWYRQ1 is AEC-Q100 Grade 1 qualified, rated for operation from –40°C to +125°C ambient temperature. It includes functional safety documentation and is designed specifically for infotainment, ADAS, and telematics systems in passenger and commercial vehicles.
How does the TPS628130AQWRWYRQ1 handle light-load efficiency?
The TPS628130AQWRWYRQ1 automatically transitions between PFM and PWM modes based on load: it enters PFM mode below ~100 mA to maintain high efficiency (up to 95% at 10 mA), then switches to fixed-frequency PWM above that threshold - ensuring >85% efficiency across 0.1 mA to 3 A output range.
