DESCRIPTION

The 78253 series of converter transformers are

specifically designed for use with the MAX253

chip set 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 bridge or

voltage doubling.

Surface-mount parts

The surface-mount (M suffix) products are not

recommended for new designs. For existing designs,

however, Murata Power Solutions will continue to

manufacture and fully support these parts.

For recommended alternatives please refer to the

78253J Series datasheet.
