Transformers are compatible with TI Fly-Buck converters.

Press Release Summary:



Designed to complement Texas Instruments LM5017 Fly-Buck™ converters, transformers in Fly-Buck series feature topology and electrical characteristics which facilitate and accelerate implementation of Fly-Buck circuit for 2 or 4 isolated outputs. Devices feature 1,500 Vrms isolation, while leakage inductance and inter-winding capacitance promote overall power conversion efficiency. All configurations handle 15–40 Vac inputs and frequencies up to 600 kHz.

Premier Magnetics' Transformers Designed for TI's Fly-Buck(TM) Converters



Transformer topology and electrical characteristics are configured specifically for use with Texas Instruments' Fly-Buck isolated synchronous buck converters



LAKE FOREST, Calif. – Premier Magnetics, global producer of high-quality magnetic components, has introduced a line of transformers specifically designed to complement the Texas Instruments LM5017 family of Fly-Buck™ converters. The Premier Magnetics Fly-Buck transformers' topology and electrical characteristics are designed to provide fast and simple implementation of the Fly-Buck circuit for two or four isolated outputs. The devices feature 1500 Vrms isolation and their low-leakage inductance and low inter-winding capacitance contribute to improved overall power conversion efficiency. For example, the TI LM5017 demo board utilizing a Premier Magnetics TSD-3425 transformer has a demonstrated efficiency of greater than 90%.



Expanding Premier's popular TSD Series, the models in the Fly-Buck series are offered to support three popular Fly-Buck circuit configurations. All handle 15-40 Vac inputs and frequencies up to 600 kHz.  The Model TSD-3424, in an EP13 package, provides quad outputs (2x +5@100 mA / 2x +15@50 mA); the dual output TSD-3425 (+5@250 mA / +5@250 mA) and TSD-3426 (+5@150 mA / +5@150 mA) are each in a smaller EP10 package.



"The new line of Fly-Buck transformers is another example of Premier Magnetics' commitment to providing well-engineered magnetics solutions to the power electronics design community," said Jim Earley, president of Premier Magnetics. "Our goal is to simplify switching power supply optimization by providing our customers with reference designs and recommended filters and power inductors to complete the task."
