This video reviews the evaluation board platform for Renesas' family of full-digital multiphase controllers. These multiphase controllers are X + Y products. There are 4-phase X + Y = 4 and 7-phase X +Y = 7 controllers. That means each product has multiple phases that can be assigned to one of two outputs, as long as the total number of phases is less than four or less than seven.

Here are our digital power eval board platforms. Here are our 2 + 2 for low-current applications, scaling all the way to a 7 + 0 for higher-current applications supporting 250+ amps of load current. Each board includes a spot for a PMBus adapter, AVSBus adapter, has an on-board transient load generator and includes our latest generation of 5mm x 5 mm smart power stages.

The smart power stage includes the MOSFETs, drivers, and provides integrated current sense and temperature sense information back to the controller. This all comes in a nice, compact solution size.
