Key Features
- AEC-Q100 automotive qualification ensuring reliable operation across the full automotive temperature range of -40 °C to +125 °C
- 2 A output current with current-mode PWM control (2.7 V to 6 V input) enabling stable 5 V and 3.3 V rail generation from automotive battery-derived supplies
- Compact SOT583-8 flat-lead package minimizing PCB area for space-constrained automotive ECU and sensor module designs
- Current-mode control architecture providing fast transient response and inherent cycle-by-cycle overcurrent protection for robust automotive power management
Applications
XPS628502QDRLRQ1 is designed for automotive ECUs, ADAS sensor modules, and in-vehicle infotainment systems requiring a reliable 2 A step-down supply from a post-regulator 5 V or 6 V bus rail. Its AEC-Q100 qualification and -40 °C to +125 °C operating range make it suitable for under-hood and body electronics operating in harsh thermal environments. The SOT583-8 flat-lead package integrates efficiently into compact 4-layer automotive PCBs where space for discrete buck regulator solutions is unavailable.

Frequently Asked Questions
What input voltage range does XPS628502QDRLRQ1 support, and does this cover a 5 V automotive post-regulator bus?
XPS628502QDRLRQ1 accepts input voltages from 2.7 V to 6 V, which fully covers the standard 5 V automotive post-regulator bus including its ±10% tolerance band from 4.5 V to 5.5 V. It also operates from low-dropout conditions at 2.7 V, making it compatible with 3.3 V intermediate bus designs in modern low-voltage ECU power trees.
What automotive qualification standard does XPS628502QDRLRQ1 meet, and what does that imply for component selection in vehicle designs?
XPS628502QDRLRQ1 carries AEC-Q100 qualification, the industry standard stress test for automotive integrated circuits, verified across a junction temperature range of -40 °C to +125 °C. AEC-Q100 compliance reduces the automotive OEM validation burden, satisfies Tier 1 supplier BOM approval requirements, and ensures traceability and process control consistent with IATF 16949 supply chain expectations.
For an ADAS radar front-end requiring a clean 1.8 V rail at 1.5 A, how does XPS628502QDRLRQ1 meet that need?
With a 2 A maximum output rating and current-mode PWM control, XPS628502QDRLRQ1 comfortably supplies 1.5 A at 1.8 V with a 25% current headroom margin. Current-mode control delivers fast transient response under abrupt load steps typical of radar DSP bursts, and the cycle-by-cycle current limit protects the rail during power-on inrush without triggering false shutdowns.
How does the SOT583-8 package of XPS628502QDRLRQ1 compare with a standard SO-8 package for thermal performance on a 2-layer automotive PCB?
The SOT583-8 flat-lead package provides an exposed thermal pad that transfers heat directly to the PCB copper pour, achieving a junction-to-board thermal resistance roughly 20 % to 30 % lower than a conventional 8-pin SOIC without an exposed pad. At 2 A output and 85 °C ambient, this translates to a junction temperature approximately 15 °C cooler, extending headroom before thermal shutdown engages in confined automotive enclosures.
