FEATURES
DESCRIPTION
The 78253 series of converter transformers are
specifi cally 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.
J-STD-020D refl ow
RoHS compliant
Maxim MAX253 compatible
3.3V and 5V versions
Isolation to 4kV
Frequency range to 500kHZ
Toroidal construction
Industry-standard pinout
UL 94 V-0 package materials
Low profi le
