NCP5380MNR2G Description

Short technical summary and product information.

The NCP5380MNR2G is a buck switching regulator controller from On Semiconductor, specifically designed for Intel VR11 voltage regulation applications. It provides a single output with a 7-bit digitally programmable DAC and achieves a worst-case ±8 mV differentially sensed core voltage error over temperature. The controller operates from multiple supply voltages and is specified over a temperature range of 0°C to 85°C.

 

This controller is ideal for precision core voltage regulation in VR11-compliant systems, such as server and desktop power supplies. The 7-bit DAC allows flexible output voltage programming, while the tight error tolerance ensures accurate regulation across temperature and load variations.

 

The NCP5380MNR2G is offered in a 32-VFQFN Exposed Pad package (also known as 32-QFN 5x5 mm), which supports surface mount assembly and provides efficient thermal dissipation through the exposed pad. The compact package is suitable for space-constrained designs requiring high performance.
