PT6100 Series  
1 Amp Adjustable Positive Step-down  
Integrated Switching Regulator  
SLTS029A  
(Revised 6/30/2000)  
The PT6100 Series is a line of High-Perfor-  
mance 1 Amp, 12-Pin SIP (Single In-line  
Package) Integrated Switching Regulators  
(ISRs) designed to meet the on-board power  
conversion needs of battery powered or other  
equipment requiring high efficiency and small  
size. This high performance ISR family offers  
a unique combination of features combining  
90% typical efficiency with open-collector  
on/off control and adjustable output voltage.  
Quiescent current in the shutdown mode is  
less than 100µA.  
• 90% Efficiency  
• Adjustable Output Voltage  
• Internal Short Circuit Protection  
• Over-Temperature Protection  
• On/Off Control (Ground Off)  
• Small SIP Footprint  
• Meets Requirements for FCC  
Part 15; Class B limits for  
Radiated Emissions  
• Wide Input Range

* ISR will operate down to no load with reduced specifications.  
** Input voltage cannot exceed 30V when the inhibit function is used.  
***See Thermal Derating chart.  
Note: The PT6100 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.
