Product details
Overview
TPS6285010MQDYCRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous step-down DC/DC converter delivering 1A continuous output current, operating from 2.7V to 6V input, with fixed 1.8V output voltage, 17µA quiescent current, and ±1% output voltage accuracy in PWM mode - used in ADAS camera power rails and infotainment domain controllers.
For engineers reviewing the TPS6285010MQDYCRQ1 datasheet, TPS6285010MQDYCRQ1 pinout, TPS6285010MQDYCRQ1 application, or TPS6285010MQDYCRQ1 equivalent, key selection criteria include its SOT583 package footprint, 1.8MHz–4MHz adjustable switching frequency, active output discharge, power-good window comparator, and functional safety documentation support for ASIL-B system integration.
Technical Context
The TPS6285010MQDYCRQ1 implements peak current mode control with internal compensation selectable via COMP/FSET pin logic or resistor biasing, enabling stable operation with 2×10µF ceramic output capacitors. Its MODE/SYNC pin supports forced PWM, PFM/PWM auto-mode transition, and external clock synchronization from 1.8MHz to 4MHz with <50µs lock time.
It integrates low-RDS(on) power FETs (65mΩ high-side, 33mΩ low-side at VIN ≥ 5V), 100% duty cycle capability, precise enable with user-defined UVLO, and thermal shutdown at 170°C with 15°C hysteresis - all qualified for –40°C to +125°C ambient operation per AEC-Q100.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 6V - supports wide automotive battery rail including cold-crank (≥2.7V) and load-dump transient margins. |
| Output Current | 1A continuous - sufficient for powering single-core SoCs, image signal processors, or LPDDR I/O rails in ADAS cameras. |
| Output Voltage | Fixed 1.8V - eliminates external feedback resistors; matches core voltage requirements of many automotive vision processors. |
| Quiescent Current | 17µA typical - enables ultra-low standby power in always-on ADAS modules without compromising wake-up latency. |
| Switching Frequency | 1.8MHz to 4MHz - allows compact 0.47µH inductor selection and EMI optimization via spread spectrum or external sync. |
| Output Accuracy | ±1% in PWM mode - ensures tight regulation for noise-sensitive analog front-ends and high-speed SerDes interfaces. |
| Package | SOT583 (8-pin, 2.10mm × 1.60mm) - thermally enhanced small-outline package with exposed pad for automotive-grade thermal performance (RθJA = 60°C/W on EVM). |
Pinout & Package
SOT583 package (8-pin, 2.10mm × 1.60mm body size including pins) with exposed thermal pad; optimized for high-density automotive PCB layouts and thermal dissipation in confined ECU spaces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 2.7V–6V supply; requires local 2×10µF ceramic input capacitance placed adjacent to pin for low-impedance path. |
| SW | Switch node | Connects to internal high/low-side MOSFETs; drives external 0.47µH inductor; critical for EMI layout and thermal routing. |
| GND | Ground reference | Primary return path for power and control circuits; must be connected to thermal pad and solid ground plane. |
| EN | Enable control | Logic-level input (1.0V threshold); supports programmable UVLO and precise power sequencing via external resistor divider. |
| PG | Power-good indicator | Open-drain output with window comparator; asserts high-Z when VOUT is within ±5% of 1.8V and device is enabled. |
| FB | Feedback input | Not used - fixed-output variant; internally tied to 1.8V reference; pin must be left unconnected per datasheet. |
| COMP/FSET | Compensation & frequency set | Configures loop compensation and switching frequency (1.8–4MHz) via resistor-to-GND or logic level (GND/VIN). |
| MODE/SYNC | Operation mode control | Selects PFM/PWM auto-mode (low) or forced PWM (high); also accepts external 1.8–4MHz sync clock signal. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - meets automotive infotainment and ADAS environmental stress requirements. |
| Active output discharge | 100Ω internal discharge path - ensures rapid VOUT ramp-down during disable, preventing back-powering of downstream circuitry. |
| Functional safety documentation | FIT rate, failure modes, and diagnostic coverage data provided - supports ISO 26262 ASIL-B hardware element development. |
| Pseudo-random spread spectrum | Reduces peak EMI emissions by up to 10dB - simplifies compliance with CISPR 25 Class 5 radiated emissions limits in vehicle cabins. |
| 100% duty cycle mode | Maintains regulation down to VIN = VOUT - essential for maintaining 1.8V rail during automotive cold-crank conditions where battery dips to ~2.7V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6285010MQDRLRQ1 | SOT583 DRL package (same pinout), identical electrical specs, but higher RθJA (110°C/W vs. 60°C/W on EVM) | Better suited for lower-power, non-thermally constrained layouts where board-level heat spreading is limited | Select when thermal vias under exposed pad are impractical and ambient temperature remains ≤85°C |
| TPS62901RTER | Non-automotive 1A buck (no AEC-Q100), 1.8V fixed, 17µA IQ, but uses 2mm × 2mm WSON package and lacks PG output | Targeted at industrial or consumer designs requiring cost-optimized footprint without automotive qualification | Choose only for non-safety-critical, non-automotive applications where AEC-Q100 and power-good signaling are unnecessary |
Compared with TPS6285010MQDYCRQ1, the DRL variant trades thermal performance for broader layout flexibility, while the TPS62901RTER sacrifices automotive qualification and system monitoring features for lower cost and smaller area - making the DYCRQ1 optimal for thermally demanding, ASIL-aware ADAS subsystems.

FAQ
What is the output voltage configuration of the TPS6285010MQDYCRQ1?
The TPS6285010MQDYCRQ1 is a fixed-output variant delivering 1.8V with ±1% accuracy in PWM mode. It does not require external feedback resistors - the FB pin is internally connected to the 1.8V reference and must remain unconnected in the design. This simplifies layout and improves reliability in space-constrained automotive modules.
Does the TPS6285010MQDYCRQ1 support external clock synchronization?
Yes, the TPS6285010MQDYCRQ1 supports external clock synchronization via the MODE/SYNC pin, accepting a 1.8MHz–4MHz square wave with 20%–80% duty cycle. The device locks to the external clock within 50µs and maintains phase alignment, enabling multi-converter EMI reduction and deterministic timing in synchronized power domains.
What thermal performance can be expected from the TPS6285010MQDYCRQ1 in automotive applications?
The TPS6285010MQDYCRQ1 in the SOT583 DYC package achieves 60°C/W junction-to-ambient thermal resistance on an evaluation board with proper thermal vias to inner ground planes. At 1A load and 4V input, typical junction temperature rise is <45°C - well within the –40°C to +150°C TJ rating and suitable for under-hood and dashboard-mounted ECUs.
How does the power-good (PG) output function on the TPS6285010MQDYCRQ1?
The PG pin on the TPS6285010MQDYCRQ1 is an open-drain output driven by a window comparator monitoring VOUT. It asserts high-impedance when VOUT is within 95%–107% of 1.8V and the device is enabled; otherwise, it pulls low. A 10kΩ pullup to VIN or 3.3V is required, and deglitch time is 40µs to reject transient disturbances.
Is the TPS6285010MQDYCRQ1 qualified for functional safety applications?
Yes, the TPS6285010MQDYCRQ1 is functional safety-capable with documentation available for ISO 26262 ASIL-B system integration, including FIT rate calculation, failure mode analysis, and diagnostic coverage guidance. It is not ASIL-certified out-of-box but provides the necessary hardware features and collateral to support safety element development.
