18 AMP “CURRENT BOOSTER”  
FOR PT7700 SERIES  
Revised 8/13/98  
The PT7749 is a new high-perfor-  
parallel output stage driven by the PT7700.  
mance 18 Amp “Current Booster” for  
the PT7700 Series housed in a 27-pin  
SIP package.  
As such, the system runs in perfect  
sychronization providing a low noise solu-  
tion.  
Multiple PT7749 boosters will oper-  
ate in parallel with the PT7700 boosting  
output current in increments of 18A .  
Combinations of PT7700s and PT7749  
current boosters can easily supply enough  
power for virtually any multiple  
megaprocessor application.  
The PT7749 only operates in combina-  
tion with the PT7700 series and is not a  
stand-alone product. Therefore please refer  
the PT7705, PT7706, or PT7707 series  
data sheet for performance specifications.  
The PT7749 also has the same mechanical  
dimensions and package options as the  
PT7700 series.

Output Capacitors: When used with a PT7705or PT7706, the PT7749 requires a minimum ouput capacitance of 1200µF. When used with a PT7707, the PT7749  
requires a minimum ouput capacitance of 330µF for proper operation. Do not use Oscon type capacitors. The maximum allowable output capacitance is 15,000µF.  
Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 18ADC with a typical value of 1µH. The input capacitance must be  
rated for a minimum of 1.3Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
