Product details
Overview
TPS6285010MQDRLRQ1 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 - deployed in ADAS camera modules and surround-view ECUs.
For engineers reviewing the TPS6285010MQDRLRQ1 datasheet, TPS6285010MQDRLRQ1 pinout, TPS6285010MQDRLRQ1 application, or TPS6285010MQDRLRQ1 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 ISO 26262-compliant systems.
Technical Context
The TPS6285010MQDRLRQ1 implements peak current mode control with internal compensation selectable via COMP/FSET pin configuration, enabling stable operation with 2×10µF ceramic output capacitance. Its MODE/SYNC pin supports forced PWM, PFM/PWM auto-transition, and external clock synchronization from 1.8MHz to 4MHz with falling-edge alignment.
It integrates precision enable logic (1.1V rising threshold, 100mV hysteresis), 100% duty cycle capability, foldback overcurrent protection (disabled per device variant), and open-drain power-good output with 92–98% rising / 87–93% falling VFB window detection - all qualified for –40°C to +125°C ambient operation and junction temperatures up to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 6V - supports direct connection to automotive 3.3V/5V rails and battery-supervised domains without pre-regulation |
| Output Voltage | Fixed 1.8V - eliminates external feedback resistors; matches I/O voltage requirements of image sensors and SerDes interfaces |
| Continuous Output Current | 1A - sufficient for powering single-lane MIPI CSI-2 camera processors or low-power MCU cores in cluster applications |
| Quiescent Current | 17µA typical - enables always-on functionality in vehicle wake-up circuits while meeting ultra-low standby power targets |
| Output Voltage Accuracy | ±1% in PWM mode - ensures stable core voltage under dynamic load transients without requiring post-regulation trimming |
| Switching Frequency Range | 1.8MHz to 4MHz - allows EMI optimization via spread spectrum or synchronization to avoid sensitive RF bands (e.g., GNSS, LTE) |
| Thermal Shutdown Threshold | 170°C with 15°C hysteresis - protects against sustained overload or poor PCB thermal design in confined ECU enclosures |
| Package | SOT583 (DRL) - 2.10mm × 1.60mm footprint with 8 terminals; enables high-density layout in space-constrained ADAS modules |
Pinout & Package
SOT583 (DRL) package: 8-pin, 2.10mm × 1.60mm body size (including pins), exposed thermal pad on bottom side for enhanced PCB heat dissipation.
| 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 decoupling |
| SW | Switch node | Connects to external 0.47µH inductor; carries high di/dt switching current - must be routed with minimal loop area |
| GND | Ground reference | Primary return path for power and signal; ties to thermal pad for thermal conduction and noise reduction |
| EN | Enable control | Logic-level input with 1.1V rising threshold; supports RC-based sequencing delay and user-defined UVLO via resistor divider |
| PG | Power-good indicator | Open-drain output requiring external pullup; asserts low during startup, UVLO, thermal shutdown, or output undervoltage/overvoltage |
| FB | Feedback reference | Not used for fixed-output variants - internally tied to 1.8V reference; pin left unconnected per datasheet |
| COMP/FSET | Compensation & frequency set | Resistor-to-GND sets switching frequency (1.8–4MHz) and control-loop compensation; tied to GND for 2.25MHz default |
| MODE/SYNC | Operation mode control | Pulled high for forced PWM; pulled low for PFM/PWM auto-mode; accepts external sync clock (1.8–4MHz) on falling edge |
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 |
| Precision enable with UVLO | 1.1V rising / 1.0V falling threshold - enables robust power sequencing and system-level brownout detection without external comparators |
| Power-good window comparator | 92–98% rising / 87–93% falling VFB detection - provides reliable rail monitoring for fault logging and safe state transitions |
| Functional safety documentation | FIT rate, failure modes, and diagnostic coverage data available - accelerates ASIL-B system-level FMEDA and safety case development |

FAQ
What is the output voltage of the TPS6285010MQDRLRQ1?
The TPS6285010MQDRLRQ1 features a factory-trimmed fixed output voltage of 1.8V. This eliminates the need for external feedback resistors and ensures ±1% accuracy in PWM operation across temperature and load. The FB pin is internally connected to the 1.8V reference and must remain unconnected in standard operation per the datasheet.
Does the TPS6285010MQDRLRQ1 support external synchronization?
Yes, the TPS6285010MQDRLRQ1 supports external clock synchronization via its MODE/SYNC pin. When driven with a clean CMOS signal between 1.8MHz and 4MHz, the device locks to the external frequency on the falling edge, enabling phase-aligned switching across multiple converters - critical for EMI reduction in multi-rail ADAS systems.
What package type does the TPS6285010MQDRLRQ1 use?
The TPS6285010MQDRLRQ1 uses the SOT583 (DRL) package: an 8-pin, 2.10mm × 1.60mm surface-mount outline with an exposed thermal pad. This compact automotive-qualified package supports high power density and efficient PCB thermal transfer, making it ideal for space-constrained camera modules and ECUs.
Is the TPS6285010MQDRLRQ1 qualified for automotive applications?
Yes, the TPS6285010MQDRLRQ1 is AEC-Q100 Grade 1 qualified for ambient temperatures from –40°C to +125°C and junction temperatures up to +150°C. It includes functional safety documentation and is designed specifically for automotive infotainment and ADAS applications including camera systems and surround-view ECUs.
What is the quiescent current of the TPS6285010MQDRLRQ1 in shutdown mode?
In shutdown mode (EN = low), the TPS6285010MQDRLRQ1 draws a typical shutdown current of 1.5µA, with a maximum of 48µA across temperature. This ultra-low leakage supports always-on vehicle functions such as intrusion detection and remote wake-up while minimizing battery drain during extended parking periods.
