30 WATT POSITIVE STEP-DOWN  
INTEGRATED SWITCHING REGULATOR  
Revised 5/15/98  
The PT3300 is a new series of high-  
nominal with the addition of an external  
input voltage, 30 Watt, non-isolated  
Integrated Switching Regulators (ISRs)  
housed in a 19-pin SIP package. The 20  
to 60 V input range allows easy integra-  
tion into many distributed power  
applications which utilize 24, 28, or 48V  
bus architechures.  
The PT3300 series is available with  
3.3, 5, 12, or 15V outputs. The output  
voltage is adjustable from 90 to 110% of  
resistor. Other easy to use features include  
an inhibit function and remote sense  
which automatically compensates for any  
voltage drop from the ISR to the load. As  
with other Power Trends’ products, the  
PT3300 includes built in current limit,  
short circuit protection and over-tempera-  
ture shutdown.  
The PT3300 requires a 330µF output  
capacitor for proper operation.
