For National Semiconductor

Planar Magnetics _{LM5041 IC}

This planar transformer and inductor pair were designed

specifically 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

offers very high current handling capability and ex-

tremely 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.
