The MAX774 ISDN ring-tone power-supply (IRG) evalua-  
tion kit (EV kit) provides the high voltages required for  
implementing a plain old telephone system (POTS) inter-  
face on ISDN modems and line cards. It is a fully assem-  
bled and tested board that provides a tightly regulated,  
-24V output for powering off-hook voice communication  
and a -70V output for on-hook, ring-tone generation.  
ꢀ +3V to +16.5V Operating Range  
ꢀ Tightly Regulated, -24V Output for Off-Hook  
Voice Communication  
ꢀ -70V Output Supports a Five-Ringer-Equivalent  
Load (V > 10.5V)  
IN  
ꢀ Compact Construction  
The EV kit is designed for applications that implement  
the telephone interface using subscriber line interface  
circuit (SLIC) ICs, such as the AM79R79 from AMD and  
comparable products from Lucent, Harris, and other  
vendors. Its design feeds back the -24V output, achiev-  
ing tight regulation for clean voice-signal transmission.  
An economical, off-the-shelf, surface-mount transformer  
reduces system cost and size. Compact design con-  
serves board area. High efficiency and reduced quies-  
cent current make this design the optimal solution for  
green PC and portable designs.  
ꢀ Proven PC Board Design  
ꢀ Uses Off-the-Shelf Components  
ꢀ Up to 84% Efficiency  
ꢀ 5µA Shutdown Current  
ꢀ Fully Assembled and Tested  
The MAX774 IRG EV kit can also be used to evaluate  
the MAX775/MAX776. It has a layout that allows modifi-  
cation for -48V output operation as well as adaptation  
for lower-voltage European applications.

Caution: Touching the MAX774 IRG EV kit’s -70V  
output can result in electrical shock. Do not touch  
the -70V output during operation or for five minutes  
after operation. Maxim assumes no liability for  
injury or damage resulting from unsafe operation of  
this EV kit.
