PT7747—24V  
15 Amp “Current Booster”  
for PT7750 Series  
SLTS050A  
(Revised 6/30/2000)  
The PT7747 is a high-perfor-  
mance 15 Amp “Current Booster” for  
the PT7750 Series housed in a 27-pin  
SIP package. Multiple PT7747 boost-  
ers will operate in parallel with the  
PT7750 Series boosting output cur-  
rent in increments of 15A .  
A PT7747 current booster adds a paral-  
lel output stage driven by the PT7750. As  
such, the system runs in perfect sychroni–  
zation providing a low noise solution.  
The PT7747 only operates in combina-  
tion with the PT7750 series and is not a  
stand-alone product. Therefore please refer  
the PT7750 series data sheet for perfor-  
mance specifications. The PT7747 also has  
the same mechanical dimensions and pack-  
age options as the PT7750 series.  
Combinations of PT7750s and  
PT7747 current boosters can easily  
supply enough power for virtually any  
multiple megaprocessor application.

Output Capacitors: The PT7750/PT7747 series requires a minimum output capacitance of 2000µF for proper operation. Do not use Oscon type capacitors. The maxi-  
mum allowable output capacitance is (42,000 ÷ Vout)µF for the PT7751, (96,000 ÷ Vout)µF for the PT7756, or 15,000µF, whichever is less.  
Input Filter: An input inductor is optional for most applications. The input inductor must be sized to handle 9ADC with a typical value of 1µH. The input capacitance  
must be rated for a minimum of 8.0 Arms of ripple current when operated at maximum output current and maximum output voltage. Contact an applications  
engineer for input capacitor selection for applications at other output voltages and output currents.
