Bourns announced the introduction of the new Model SM91047EL flyback transformer, designed for off-line AC-DC power supply applications.
The device is an 11,875 : 1, (primary : secondary) turns ratio flyback transformer with 1,5 kVrms isolation. The input voltage range is 100 - 375 V d.c., 50 kHz switching frequency regulated to 5 V /0,4 A d.c. output. This transformer is designed to meet IEC 60950-1 functional grade of insulation, and is suitable for use with Texas Instruments’ UCC28880 low quiescent current off-line converter.
Applications for the RoHS compliant device include AC-DC power supplies, metering, home automation, appliances, white goods and LED drivers.
