NB679GD-Z Description

Short technical summary and product information.

The Monolithic Power Systems NB679GD-Z is an integrated circuit designed for power management applications, offering both step-down (buck) synchronous and linear (LDO) regulation.

 

This device provides two outputs and operates at a switching frequency of 700kHz. It is designed for a 5V output voltage and can handle an output current of 100mA. The operating temperature range is from -40°C to 125°C (TJ).

 

The NB679GD-Z comes in a 12-QFN (2x3) package, specifically a 12-PowerVFQFN, and is designed for surface mount applications. It adheres to RoHS3 compliance standards and has an MSL of 1.

 

This dual regulator is suitable for applications requiring efficient power conversion and stable voltage outputs, combining the benefits of buck converters for efficiency and LDOs for low noise.
