ISE engineers and produces customer-specific chokes and transformers for switch mode power supplies, and DC/DC converters, among others.
For the most common ICs (such as from Linear Technology, National Semiconductors and Power Integrations), ISE has developed a standard series of chokes and transformers. However, their specialty is customer-specific solutions, occasionally deriving from these standard components.
Chokes: Transformers:
Common mode choke coils Fly back transformers
Storage chokes Forward
Power factor correction Push-Pull
dI/dt and dV/dt chokes Half- / Full Bridge
Input / output filter chokes Resonance conversion
Current chokes Current transformers
Suppression chokes Impedance transformers
