2 AMP ADJUSTABLE POSITIVE STEP-DOWN  
INTEGRATED SWITCHING REGULATOR  
• 87% Efficiency  
Switching Regulator (ISR) designed to  
• Adjustable Output Voltage  
• Internal Short Circuit Protection  
• Over-Temperature Protection  
• On/Off Control (Ground Off)  
• Small SIP Footprint  
meet the on-board power conversion  
needs of battery powered or other equip-  
ment requiring high efficiency and  
small size. This high performance ISR  
offers a unique combination of features  
combining 87% typical efficiency with  
open-collector on/off control and ad-  
justable output voltage.  
• Wide Input Range  
The PT6310 series is a High-  
Performance 2 Amp, 12-Pin SIP  
(Single In-line Package) Integrated  
Quiescent current in the shutdown  
mode is typically less than 100µA.

ISR will operate to no load with reduced specifications.  
** Input voltage cannot exceed 30V when the inhibit function is used.  
Note: The PT6310 requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.
