For National Semiconductor

LM5115 DC Controller IC

SMT Power Inductor

The D1787-AL was developed for use with the National

Semiconductor LM5115 Secondary Side Post Regula-

tor Controller and LM5025 Primary Side Controller. This

flat wire power inductor offers extremely low dc resis-

tance and very high current ratings (up to 23 Arms).

The flat core allows for exceptional heat dissipation

and provides an excellent surface for pick and place

operation.

This inductor is ideal for power supply applications where

high current handling is essential and is perfect for low-

voltage dc-dc converters. Custom inductance values are

also possible.
