NB679GD-P

Overview

The NB679GD-P is a synchronous step-down converter manufactured by Monolithic Power Systems. It features a fixed 5V output and supports up to 8A of output current. The device operates with an input voltage range from 5.5V to 26V. Internal switching frequency is set at 700kHz. Quiescent current is specified at 100uA. The component utilizes a QFN-12 package for surface mount installation.

Feature Summary

• Synchronous buck topology for efficient power conversion
• Fixed output voltage configuration
• Integrated shutdown control functionality

Applications

• Point-of-load regulation in embedded systems
• Power distribution networks requiring stable 5V rails
• Industrial equipment power management

Procurement Notes

Verify availability status carefully as the part may be subject to limited supply or factory special orders. Confirm RoHS compliance details through official documentation before integration. Ensure the QFN-12 package footprint matches the design layout requirements. Check for any specific handling instructions related to the surface mount technology used.

Selection Notes

Select this component when a fixed 5V output is required with high current capability up to 8A. The 700kHz switching frequency allows for compact external component sizing. Consider the 5.5V to 26V input range for compatibility with various bus voltages. The integrated shutdown feature aids in system power management strategies.

Part Context

This part belongs to the NB679 series of synchronous buck converters from Monolithic Power Systems. It is designed for applications needing reliable DC-DC conversion with fixed output settings. The series targets general-purpose power management needs in industrial and consumer electronics sectors.

Replacement Considerations

Check for NB679AGD-P if a 5.1V fixed output is acceptable instead of 5V. Verify pinout and thermal performance compatibility before substitution.
