IR3502 Overview
The IR3502 control IC bined with an XPHASE3TM Phase IC provides a full featured and flexible way to implement a plete VR11.0 and VR11.1 power solution. The IR3502 provides overall system control and interfaces with any number of Phase ICs, each driving and monitoring a single phase. The XPhase3TM architecture results in a power supply that is smaller, less expensive, and easier to design while providing higher...
