6 Pin, 3KVrms DC/DC Converter
Isolation Modules
The TGM-NA and TDM-NA, reinforced insulation, 6 pin transformers provide the isola-
tion and voltage outputs required for low cost DC/DC converter circuits. UL1950, IEC950
and EN60950 recognized. Designed specifically for use with the Maxim™ MAX253 and
MAX845 monolithic oscillator/power drivers with 3.3V or 5V power source. Other pack-
ages are available with isolation voltages ranging from 500 to 4.5KVrms. For more
information, pertaining to the MAX845 please contact Maxim at (408) 737-7600. Maxim
