NCV6357MTWATXG

Overview

The NCV6357MTWATXG is a synchronous Adaptive On-time (AOT) buck converter designed for automotive subsystems. It operates with an input voltage range of 2.5V to 5.5V and delivers up to 5A output current. The device features a fixed switching frequency of 2.4 MHz and supports adjustable output voltages from 600 mV to 3.3 V. Quiescent current is specified at 22 mA. It is qualified under AEC-Q100 standards and functions within a junction temperature range of -40°C to +125°C, housed in a 14-WDFNW package.

Feature Summary

• Synchronous Adaptive On-time topology optimized for automotive applications
• Fixed 2.4 MHz switching frequency for compact external component sizing
• AEC-Q100 qualified for automotive reliability requirements

Applications

• Automotive ADAS power solutions
• Infotainment system voltage regulation

Procurement Notes

Verify the complete part number against official onsemi documentation to ensure correct suffix alignment. Confirm that the specific suffix matches the required operational mode and packaging configuration. Cross-reference the manufacturer's latest datasheet to validate electrical parameters and pinout compatibility before integration into design specifications.

Selection Notes

Select this component for designs requiring a robust, automotive-grade synchronous buck regulator. The fixed 2.4 MHz frequency simplifies filter design compared to variable frequency alternatives. Ensure the thermal management strategy accommodates the WDFNW-14 package constraints and the specified operating temperature range for reliable performance in vehicle environments.
