Description

This product utilizes the 5th generation of design

rules of ST’s proprietary STripFET™ technology.

The lowest available RDS(on)*Qg, in this chip scale

package, makes this device suitable for the most

demanding DC-DC converter applications, where

high power density is to be achieved.
