PT7741—5V  
32 Amp “Current Booster” for  
PT7775/PT7779 Regulators  
SLTS118  
(Revised 8/31/2000)  
Description  
The PT7741 is a high-output 32  
Amp “Current Booster” designed to  
The booster adds a parallel output  
stage that is driven directly by the  
regulator. Both operate in perfect  
sychronization for a low noise solution.  
The PT7741 only operates with  
the PT7775 and PT7775 regulators.  
It is not a stand-alone product. Please  
refer to the appropriate data sheet for  
the performance specifications. The  
current booster has the same package  
options as the companion regulators.  
operate with the PT7775 and  
PT7779 regulators. Up to two  
PT7741 boosters will operate in  
parallel with one regulator, boosting  
output current in increments of 32A.  
Combinations of one regulator and  
PT7741 current boosters can supply  
enough power for virtually any mul-  
tiple mega-processor application.

External Capacitors: When used with a PT7779, the PT7741 requires a minimum ouput capacitance of 330µF. The maximum allowable output capacitance is  
30,000µF. The PT7741 also requires a minimum input capacitance of 2400µF, which must be rated for a minimum of 2.0Arms of ripple current. For transient  
or dynamic load applications, additional capacitance may be required. For further information, see the accompanying application note on capacitor selection for this  
product.  
Input Filter: An input filter inductor is optional for most applications. The input inductor must be sized to handle 32ADC with a typical value of 1µH.
