NCV6357MTWCTXG

Overview

The NCV6357MTWCTXG is a synchronous buck DC-DC converter from onsemi, designed for high-efficiency power management in automotive and industrial applications. It operates with an input voltage range of 2.5 V to 5.5 V and delivers up to 5 A of output current. The device features a fixed switching frequency of 2.4 MHz and supports adjustable output voltages between 600 mV and 3.3 V. Packaged in a WDFNW-14 footprint, it meets AEC-Q100 qualification standards and functions reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Synchronous step-down topology optimized for high efficiency and low noise operation
• Fixed 2.4 MHz switching frequency enabling compact external component sizing
• AEC-Q100 qualified for robust performance in demanding automotive environments

Applications

• Automotive infotainment systems requiring stable power rails
• ADAS sensor modules needing efficient voltage regulation
• Industrial control units operating under wide temperature variations

Procurement Notes

Verify the complete part number including suffixes such as 'CTXG' against official datasheets to ensure correct output voltage configuration and packaging type. Confirm AEC-Q100 compliance requirements match your specific application standards before ordering. Cross-reference manufacturer documentation for any recent design changes or obsolescence notices.

Selection Notes

Select this component when a single-output buck converter with 5 A capability is required for automotive-grade designs. Ensure the input voltage stays within the 2.5 V to 5.5 V range. Consider the WDFNW-14 package size constraints during PCB layout planning. Verify thermal dissipation needs based on the expected load current and ambient temperature conditions.

Part Context

This part belongs to the NCV6357 series of synchronous buck regulators from onsemi. The series is characterized by its high-frequency operation and automotive qualification. Other variants in the family may differ in fixed output voltage options or specific packaging configurations while maintaining similar electrical characteristics and functional blocks.

Replacement Considerations

Check for direct pin-compatible alternatives within the same NCV6357 family that offer different fixed output voltages. Verify if other manufacturers provide equivalent 5 A automotive buck converters with compatible 2.4 MHz switching frequencies and WDFNW-14 packages.
