NCV6357MTWBTXG

Overview

The NCV6357MTWBTXG is an automotive-grade synchronous step-down (Buck) switching regulator manufactured by onsemi. It operates within an input voltage range of 2.5 V to 5.5 V and delivers a maximum output current of 5 A. The device features a fixed switching frequency of 2.4 MHz and provides an adjustable output voltage from 600 mV to 3.3 V. It is qualified under the AEC-Q100 standard for automotive applications. The component supports operation across a temperature range of -40°C to +125°C and utilizes a 14-WDFNW (4x3) package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Synchronous Adjustable Output Topology (AOT) architecture
• High efficiency performance at 2.4 MHz switching frequency
• Robust thermal capability for extended industrial temperatures

Applications

• Automotive power distribution systems
• Advanced Driver Assistance Systems (ADAS) power regulation
• Infotainment system voltage conversion
• Instrument cluster power management

Procurement Notes

Verify the specific suffix 'BTXG' against the official datasheet to confirm the exact output voltage configuration, as variants within the NCV6357 series may differ in fixed output settings. Ensure that the 14-WDFNW package dimensions align with the target PCB footprint. Confirm AEC-Q100 compliance requirements are met for the intended automotive application environment before finalizing procurement.

Selection Notes

Select this component when designing for automotive environments requiring high current density and wide input voltage flexibility. The 5 A output capacity suits load-heavy subsystems, while the 2.4 MHz frequency allows for smaller external passive components. Consider the WDFNW-14 package for space-constrained layouts. Validate thermal dissipation capabilities given the 125°C junction temperature rating.

Part Context

This part belongs to the NCV6357 series of synchronous buck regulators designed specifically for automotive electronics. The series offers flexible output configurations and robust protection features suitable for harsh automotive electrical environments. It serves as a key power management solution for converting higher battery voltages to lower logic and sensor supply levels.

Replacement Considerations

Check for NCV6357MTWDTXG if a different fixed output voltage is required. Verify pinout compatibility and thermal pad specifications when substituting with other Buck regulators from competing manufacturers.
