For ON Semiconductor
NCP1027
Flyback Transformer
The DA2077-AL flyback transformer has been specifically
developed for use with ON Semiconductor’s NCP1027
Standby Power Supply for ATX Applications and is speci-
fied in Application Note AND8241/D.
This transformer is designed for universal input, 85 –
265 Vac. It operates in continuous conduction mode
within an input voltage range of 120 Vdc to 375 Vdc and
at a 65 kHz switching frequency. Primary to secondary
isolation is 2000 Vrms tested for one minute.
Coilcraft can also custom engineer a transformer to meet
your specific requirements. For free evaluation samples,
