Isolation transformer 78253 series

encapsulatedfor medical applicationsfor DC/DC converters

The 78253J series of converter transformers are specifically designed for use with the MAX253 chip set to provide isolated power supplies. The 5V input version can supply 1W and the 3.3V input version can supply 500mW. A centre tapped secondary winding allows for full bridge, half bridge or voltage doubling. For through hole versions see 78253 series datasheet.
