25VT6A5VGEVB

25VT6A5VGEVB Evaluation
Board User'sManual

Description

The 25VT6A5VGEVB evaluation board is designed such

that it can accommodate a 1x1 to a 2x2 combination of
MOSFETs, for 

m

8

FL and SO8

FL packages. Depending

on the type of application and necessity, any combination of
the above packages can be used. The 25VT6A5VGEVB
evaluation board is designed to operate with an input voltage
ranging from 8 V to 16 V, and to provide an output voltage
of 0.8 V to 1.8 V for load currents of up to 25 A. The
25VT6A5VGEVB comes with a 5 V driver. The
25VT6A5VGEVB evaluation board has a number of test
points that can be used to evaluate its performance in any
given application.
