3. Power Dissipation

Board-mounted power dissipation ratings for TCK206G, TCK207G and TCK208G are available in the Absolute Maximum

Ratings table

Power dissipation is measured on the board condition shown below.

[The Board Condition]

Board material: Glass epoxy (FR4)

Board dimension: 40mm x 40mm (both sides of board), t=1.8mm

Metal pattern ratio: a surface approximately 50%, the reverse side approximately 50%

Through hole: diameter 0.5mm x 28

Please allow sufficient margin when designing a board pattern to fit the expected power dissipation. Also take into

consideration the ambient temperature, input voltage, output current etc. and applying the appropriate derating for allowable

power dissipation during operation.
