PT6400 Series  
3 Amp 5V Input Adjustable  
Integrated Switching Regulator  
SLTS032A  
(Revised 6/30/2000)  
allows easy integration of low-power  
3.3V logic IC’s into existing 5V systems  
without redesigning the central power  
supply. Only two external capacitors are  
required for proper operation. The out-  
put voltage is easily adjustable with one  
external resistor. The PT6406,7,8 can  
be used to terminate high-speed data  
buses such as Futurebus (+2.1V) or the  
new GTL (+1.2V) logic buses.

Small SIP Footprint  
Adjustable Output Voltage  
The PT6400 is a high performance  
+5V to +3.3V, 3 Amp, 12-Pin SIP  
(Single In-line Package) Integrated  
Switching Regulator (ISR) designed  
for stand alone (not parallelable) op-  
eration. This high-performance ISR  
Please note that this product does  
not include short circuit protection.
