Application efficiency
Designing a boost application a typical constraint is the maximum output current ripple.
Once frequency, input and output voltage are defined, this constraint directly affects the
inductance value to place in the application:
Inductance value can be designed for a single ended architecture and then divided by 4 in
case of IL-4 architecture.
Each inductor, due to its internal resistance (R
efficiency. For high current application, inductor with a compact geometry risks to miss the
efficiency requirements.
In fact, using the same ferromagnetic material, higher inductance can be achieved by
increasing the inductor geometry, or by increasing the number of spins but using a thinner
wire.
In order to save space and cost, the latter solution is preferred but impacts the internal
resistance (increases) and the saturation current (reduces) of the inductor.
