GENERAL APPLICATION INFORMATION

Premier Magnetics' Switch Mode Output transformers have been designed for use with the most popular current-

mode switching regulators such as Linear Technologies LT1X7X & National Semiconductors LM25XX series of High

Efficiency Switching Regulators. These output transformers have been optimized to provide maximum power

throughput in the smallest packages currently available. This combination of components finds wide use in

Distributed Power Systems where a main dc voltage bus is converted for use on or near the circuits being served.

These types of switching regulators provide a very simple solution to power conversion designs. The inductor or

transformer used are critical to the overall performance of the converter and typically define the overall efficiency,

output power and physical size.

The following tables of transformers were designed for use in the Flyback Buck-Boost circuit configuration. This

conversion topology allows the output voltage to be regulated higher or lower than the input voltage. It can also

provide isolated or non-isolated multiple outputs. Typical efficiency of this topology is 75%.

Below is a typical application circuit utilizing Linear Technologies LT1X7X switching regulator in the flyback buck-

boost configuration. The use of Premiers VTP-01XXX or VTK-01XXX optional output filter choke will drastically reduce

output ripple and noise. The component values listed are intended for reference purposes only. The Output Filter(s),

Damper Network & Foldback Current Limiting Network are optional depending on the specific application.
