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 minimizes EMI.
The 76253/XXEN converter transformer is specifically designed for use with MAX253 chipset to provide isolated power supplies. The 5V version can supply 1W and the 3.3V version can supply 500mV. A centre tapped secondary winding allows for full bridge, half bridge or voltage doubling.
