DESCRIPTION
The 76250EN converter transformer is
specifically designed for use with Maxim
chipsets to provide isolated RS232 interfaces.
A carefully controlled turns ratio ensures
consistent performance whilst a toroidal
construction minimises EMI.
The 76253/XXEN converter transformers
are specifically designed for use with the
MAX253 chipset to provide isolated power
supplies. The 5V version can supply 1W
and the 3.3V version can supply 500mW.
A centre tapped secondary winding allows
for full bridge, half bride or voltage doubling.
The devices are fully approved to BS EN
60950 for use in telecoms applications.
