NCV6357MTWFTXG

Overview

The NCV6357MTWFTXG is a synchronous step-down switching regulator manufactured by onsemi, designed for high-efficiency power conversion in automotive and industrial applications. It operates with an input voltage range of 2.5 V to 5.5 V and delivers a fixed output voltage of 1.1 V at up to 5 A output current. The device features a fixed 2.4 MHz switching frequency and maintains a typical quiescent current of 22 mA. It is qualified under the AEC-Q101 standard for automotive reliability and functions within a junction temperature range of -40°C to +125°C. The component is housed in a WDFNW-14 package.

Feature Summary

• Fixed-frequency pulse-width modulation operation at 2.4 MHz for consistent noise spectrum management
• Automotive-grade qualification compliant with AEC-Q101 standards for enhanced reliability
• Integrated shutdown control for system power management and standby current reduction

Applications

• Automotive infotainment systems requiring stable low-voltage power rails
• Industrial control modules utilizing 5V input bus architectures
• Embedded computing platforms needing high-current step-down regulation

Procurement Notes

Verify the specific suffix 'TXG' confirms tape-and-reel packaging configuration. Confirm AEC-Q101 automotive qualification status matches project requirements. Ensure compatibility with WDFNW-14 thermal pad soldering processes. Validate that the fixed 1.1 V output aligns with target load specifications without external adjustment needs.

Selection Notes

Select this part when a fixed 1.1 V output is required from a 2.5–5.5 V source. Choose over adjustable variants if external resistor networks are undesirable. Consider the 5 A current capability against peak load demands. Verify AEC-Q101 compliance is mandatory for the intended deployment environment.

Part Context

This component belongs to the NCV6357 series of synchronous buck regulators from onsemi. The series offers various output voltage options and packaging configurations. The NCV6357MTWFTXG specifically denotes the fixed 1.1 V output variant with automotive qualification and reel packaging.

Replacement Considerations

NCV6357MTWDTXG provides similar topology but features an adjustable output voltage range (600 mV to 3.3 V) instead of a fixed 1.1 V output.
