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.
