MagI³C Power Module

VDRM – Variable Step Down Regulator Module

From the graph a power loss of 640mW is read. Entering the values in formula (21) results in:

125°C-85°C

θ_CA(MAX)

-1.9°C/W=60.6°C/W

0.64W

θ_JA(MAX)=θ_JC+ θ_CA(MAX)=1.9°C/W+60.6°C/W= 62.5°C/W

In order to achieve a θ_ꢅꢆ< 62.5°C/W it would be sufficient to use the minimum area for placing the external components, in

accordance with the indications in the “LAYOUT RECOMMENDATION” section on page 39.
