Planar Magnetics For National Semiconductor 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 highcurrent 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 extremely 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.
