Product details
Overview
STEVAL-A6983CV1 from STMicroelectronics is an automotive-grade evaluation board based on the A6983CQTR synchronous step-down DC-DC converter, delivering up to 3 A output current with 25 µA quiescent current, 3.5–38 V input range, and programmable 200 kHz–2.2 MHz switching frequency in a QFN16 (3 × 3 mm) package. It supports power-good monitoring, internal soft-start, overvoltage protection, and spread-spectrum modulation for EMC improvement - designed specifically for body electronics in parked-car applications.
For engineers reviewing the STEVAL-A6983CV1 datasheet, STEVAL-A6983CV1 pinout, STEVAL-A6983CV1 application, or STEVAL-A6983CV1 equivalent, this board enables rapid validation of the A6983CQTR's light-load efficiency, thermal behavior under 150 °C junction temperature, sequencing capability, and robustness in automotive 12 V/24 V battery systems with transient voltage tolerance.
Technical Context
The STEVAL-A6983CV1 implements a peak current mode control architecture with internal compensation, eliminating external loop components and reducing layout sensitivity. It integrates dual high-side/low-side MOSFETs, a dedicated PGOOD open-collector output, and pulse-by-pulse current sensing across both power switches for precise constant-current limiting.
Designed for AEC-Q100 Grade 1 compliance, the board validates the A6983CQTR's operation across –40 °C to +150 °C junction temperature, featuring VIN-compatible enable logic, bootstrapped gate drive (BOOT/VIN2), and dual ground domains (SGND1/SGND2, PGND1/PGND2) to support noise-isolated power delivery in automotive ECU environments.

FAQ
What is the primary function of the STEVAL-A6983CV1?
The STEVAL-A6983CV1 is an evaluation board-not a standalone IC-that demonstrates the A6983CQTR synchronous buck regulator. It provides a fully assembled, tested platform to validate performance metrics including light-load efficiency, thermal behavior at 150 °C junction temperature, sequencing, and EMC with spread spectrum enabled. It includes all necessary passives, test points, and jumper options for configuration.
Does the board support adjustable output voltage?
Yes. Output voltage is set by the FB resistor divider (R4 = 82 kΩ, R3 = 402 kΩ on the schematic), yielding a nominal 5.0 V output. The A6983CQTR supports adjustable outputs from 0.85 V to VIN via external feedback resistors, and the board's layout accommodates alternative resistor values for reconfiguration without soldering changes to core power components.
Can the STEVAL-A6983CV1 be used for functional safety (ISO 26262) development?
No. While the A6983CQTR is AEC-Q100 Grade 1 qualified and includes safety-relevant features (PGOOD, OVP, thermal shutdown), the STEVAL-A6983CV1 evaluation board itself has no FMEDA report, safety manual, or ASIL decomposition documentation. It serves as a performance validation tool-not a safety-certified hardware platform-for preliminary system-level testing prior to ASIL-targeted design.
What are the key test points and their functions?
TP1 (VIN), TP2/TP4/TP8 (GND), TP3 (VOUT), TP5 (EN), TP6 (CLKIN), TP7 (PGOOD), and TP8 (GND) provide direct access to critical signals. TP7 delivers an open-collector PGOOD signal pulled high via external 10 kΩ resistor; TP5 allows external enable control; TP6 permits external clock synchronization or frequency programming; all support oscilloscope probing and real-time monitoring without soldering.
