NCV97400MW00R2G

Overview

The NCV97400MW00R2G is an automotive-grade step-down current mode switching controller manufactured by onsemi. It operates within a 4.1 V to 40 V input voltage range and supports up to five independent outputs. The device features a fixed switching frequency of 2 MHz and utilizes a QFNW-32 package. Designed for high reliability, it meets AEC-Q101 qualification standards and functions across an extended temperature range from -40°C to +150°C.

Feature Summary

• Supports multiple output configurations with integrated current mode control
• Automotive qualified for harsh environment operation
• High switching frequency enables compact passive component sizing

Applications

• Automotive battery-connected power distribution systems
• Multi-rail power management units in vehicles
• General automotive electronics requiring isolated or non-isolated buck conversion

Procurement Notes

Verify the specific suffix MW00R2G against the official datasheet to confirm output configuration and pinout compatibility. Ensure the procurement channel provides valid traceability documentation required for automotive supply chains. Confirm that the component meets the latest AEC-Q101 reliability standards before integration into final assemblies.

Selection Notes

Select this controller when designing systems requiring multiple regulated outputs from a single high-voltage rail. The 2 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the QFNW-32 thermal performance and ensure adequate PCB copper area for heat dissipation during high-load operations.

Part Context

This component belongs to the NCV97400 series of multi-output switching controllers. It shares architectural similarities with other members like the NCV97311 but offers distinct output counts and packaging options. The series targets complex automotive power architectures needing synchronized or independent regulation channels.

Replacement Considerations

Direct substitutes include other NCV97400 variants with different suffixes indicating package or tape/reel variations. Cross-reference pinouts and electrical specifications carefully when considering alternative manufacturers' parts to ensure functional equivalence.
