Introduction

The EVBD4400 evaluation board implements a single

power phaseleg circuit on a double sided PCB with

BRIDGE DRIVER CHIPSET - IXBD4410, IXBD4411,

IXDP630. The IXDP631 is optional. This board includes

all parts required for the circuit implementation so that

you can just follow the instructions in this document and

connect the board to the load and power. The kit

consists of an assembled and tested PCB with two

power devices.

Any power circuit is layout sensitive. The layout of this kit

is a proven, working layout. The designer is invited to

duplicate this layout in his system, following the evaluation

ofthedriverchipset.

Most systems vary in their power level requirements and

therefore the power devices used. Due to this fact and

fluctuations in availability of power devices, the kit will not

always include the same power devices. The designer is

encouraged to use the power devices that are required for

his system. The devices that are enclosed serve only for

initialevaluation.
