CHVM2 Series

TDK­Lambda

<Page>

■ Recommended pattern

(1) The CHVM series uses a metallic case. When mounting to a double­sided PCB, the wiring for the converter

Should be on the soldering side.
Also, this converter will generate high voltages so the creepage distance of pattern should be taken in when 
designing.

(2) When mounting to a double­sided PCB, the land of  the parts side of the  high voltage output pin should be as 

small as possible.

(3) The case of CHVM series should be connected to the ­Vin and Vout (Com).
(4) The metallic case does not need to be connecting to ground.

However, when using and ground with the metallic case, make the impedance lower as possible between the
ground.
