8 Pin, 4.5kVrms DC/DC
Converter Isolation Modules
The TGMR-4xxV8LF, reinforced insulation, 8 pin transformer series provides the isolation
and voltage outputs required for low cost DC/DC converter circuits. Designed specifi-
cally for use with the Maxim™ MAX253 and MAX845 monolithic oscillator/power drivers
with 3.3V or 5V power source. UL60950 and EN60950 recognized. As well, this series
is ROHS compliant and “lead free”. Smaller packages are available for lower isolation
voltage applications. For more information, pertaining to the MAX253 or MAX845 please
contact Maxim at (408) 737-7600.
