NCP5351MNR2G

Overview

The NCP5351MNR2G is a synchronous buck power MOSFET driver from onsemi, designed for high-efficiency DC-DC conversion. It features a 4 A peak output current capability with independent source and sink drivers. The device operates within a supply voltage range of 5 V to 13.2 V and supports PWM or VID-based control interfaces. Packaged in an 8-pin DFN (DFN-8) surface-mount package, it integrates protection features such as under-voltage lockout and thermal shutdown. This component is optimized for point-of-load applications requiring fast transient response and compact board space.

• Industrial equipment power supplies

Procurement Notes

Verify the complete part number including the suffix 'R2G' which indicates the specific tape and reel packaging configuration. Confirm that the ordering code matches the exact pinout and electrical specifications required for your schematic. Cross-reference the manufacturer's latest datasheet to ensure compliance with current RoHS standards and material declarations before finalizing procurement orders.

Selection Notes

Select this driver when a 4 A output current capacity is sufficient for the target MOSFET gate charge requirements. Ensure the input supply voltage aligns with the 5 V to 13.2 V operating range. Consider the DFN-8 package dimensions against available PCB real estate. Evaluate whether the integrated protection features meet the safety requirements of the specific application environment without needing external components.

Part Context

This component belongs to the NCP5351 series of synchronous buck gate drivers. It is part of onsemi's portfolio aimed at improving power density and efficiency in modern electronic systems. The series is commonly used in applications where reliable high-current switching is critical, serving as a key interface between digital control logic and power stage MOSFETs.

Replacement Considerations

Check for direct pin-to-pin compatible alternatives within the same family or from other manufacturers offering similar 4 A synchronous buck drivers. Verify that any substitute maintains the same control interface compatibility and voltage range. Ensure the replacement package matches the DFN-8 footprint to avoid PCB redesign efforts.
