For National Semiconductor  
PlanarMagnetics LM5041 IC  
Coilcraft introduces a planar transformer and planar in-  
ductor for National Semiconductor’s LM5041 IC.  
The A9786-A transformer is engineered for use in high-  
current telecom power supply applications that require  
high efficiency in a low-profile package.The auxiliary  
winding can be used to control input current to PWMs. It  
offersveryhighcurrenthandlingcapabilityandextremely  
low DC resistance in a low profile package.  
Coilcraft’s A9787-A inductor is designed as the output  
choke for the LM5041.  
Planar magnetics offer high power densities along with  
great reliability and repeatability. Windings are etched  
into a printed circuit board, ensuring high efficiency and  
consistency.
