STEVAL-IFP010V3 connectors

The demonstration board is equipped with input and output connectors. Specifically, there

are two input header connectors (J5 and J1), one two-channel output channel connector

(M1) and a supply voltage connector (M2).

Both input connectors, J5 and J1, provide the same bidirectional signals guaranteeing the

maximum compatibility with existing STMicroelectronics tools such as the industrial

communication board (see AN2451) and similar products.

STEVAL-IFP010V3 thermal management

The STEVAL-IFP010V3 PCB has two heatsinks: approximately 2 sq. cm on the top layer

and 3 sq.cm on the bottom layer, thermally interconnected through 9 vias, as shown in

current limitation and in fast demagnetization, the power dissipation is much higher,

requiring a low thermal resistance through the device exposed tab, soldering space, top

layer, vias and bottom layer path. A 25 µm copper (10 oz/sq. ft) thickness and 0.3 mm

diameter for the vias are used according to EIA/JESd51-5.
