Flyback Transformer ForTexasInstruments LM5000 DC/DC Regulator
This surface mount flyback transformer is designed for use with Texas Instruments LM5000 DC/DC regulator. The core completely encloses the windings to minimize EMI interference.The transformer features very low DCR, 500 Vrms isolation and a leakage inductance rating of just 1.0 µH. Coilcraft can also custom engineer a transformer to meet your specific requirements. For free evaluation samples, contact Coilcraft or order them on-line at www.coilcraft.com.
