OPERATION NOTES
?There is fear of destruction of the internal circuit in case that input voltage exceeds the absolute maximum ratings (36V) by such as a surge
occurred because of rapid start-up of power voltage. Be sure not to exceed absolute maximum ratings even momentarily.
?This product has a protection element for safety. The protection element is fused for safety when the current which the protection element will
fuse. Please evaluate sufficiently at using environment about the action when the output circuit shorts.
?There are some case that the module generates heat exceeding allowable maximum surface temperature when the load current which exceeds
the maximum output current is flowed. Please make design keeping enough margins not to exceed allowable maximum surface temperature at
any time under any application or any test conditions.
?The aluminum board at back part of the product is connected to GND.
Please mind the arrangement not to contact surrounding parts.
?When using the module with bent lead pin, it might be destroyed with an extreme stress for the PCB or the aluminum board. Please use the
module without bending the lead pin.
?The aluminum board in the back might come off when an excessive stress is put in the direction of the thickness. When fixing to the heat sink
etc. to use this product, please mount to PCB after fixing to the heat sink and both the heat sink and this hold to PCB.
