NCV6357MTWDTXG

Overview

The NCV6357MTWDTXG is a buck DC-DC converter IC from onsemi, designed for automotive applications. It operates with an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 1.25V. The device supports up to 5A output current across one output channel. Key electrical parameters include a switching frequency of 2.4MHz, a static current of 22mA, and load regulation of 5mV. It functions within a temperature range of -40°C to +125°C and holds AEC-Q100 qualification.

Feature Summary

• Fixed 1.25V output configuration simplifies design for specific voltage rails
• Automotive-grade reliability with AEC-Q100 qualification
• Compact 14-WDFNW package with wettable flanks for improved solder joint inspection

Applications

• Automotive power conversion systems
• ADAS pre-regulator circuits
• Infotainment system power distribution

Procurement Notes

Verify the exact suffix matches NCV6357MTWDTXG to ensure the correct fixed 1.25V output variant. Confirm AEC-Q100 qualification status is required for your specific automotive application. Check datasheet for thermal performance under maximum load conditions. Ensure PCB layout adheres to the recommended footprint for the 14-WDFNW package to maintain electrical integrity.

Selection Notes

Select this component when a fixed 1.25V output is required for automotive subsystems. It is suitable for designs needing high efficiency at 2.4MHz switching frequency. Consider the 5A current capability for powering multiple loads from a single rail. The fixed output eliminates external resistor network requirements, reducing BOM complexity compared to adjustable variants.

Part Context

This part belongs to the NCV6357 series of buck regulators from onsemi. The series includes other variants with different fixed output voltages, such as 1.1V or 3.3V options. All members share similar topology and packaging but differ in internal feedback references. The NCV prefix indicates automotive-grade qualification standards.

Replacement Considerations

Direct substitutes include other NCV6357 variants with different fixed outputs like NCV6357MTWFTXG (1.1V) if voltage adjustment is possible. Cross-reference with onsemi's official replacement guide for pin-compatible alternatives. Verify that any substitute maintains the same 14-WDFNW package dimensions and thermal characteristics.
