:: DE S I G N E X A M P L E : :

Highlights
•t High efficiency (low losses), ultra compact, low-profile
•t Excellent solderability (Pb-free or Pb/Sn Solder)
•t Standard sizes / customer configurations
•t Quick custom turn-around often without start-up or tooling costs
•t Inductors available for design in all packages
•t Large secondary pins reduce temperature rise on
terminals
