P Premier M Magnetics Inc. "INNOVATORS IN MAGNETICS TECHNOLOGY" ! Designed for use with Leading Controller Chips # Provides DC/DC Conversion & Isolation GENERAL APPLICATION INFORMATION SWITCH MODE DC/DC POWER CONVERSION TRANSFORMERS " Design Engineenring Support Available. $ Multiple Configurations. Premier Magnetics' Switch Mode Output transformers have been designed for use with the most popular currentmode 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 buckboost 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.
