PT6640 Series  
24W 12V Input Positive to Negative  
Voltage Converter  
SLTS037A  
(Revised 6/30/2000)  
The PT6640 series is a positive  
input to negative output line of  
Integrated Switching Regulators  
(ISRs). Designed for general purpose  
applications, the PT6640 series deliv-  
ers a negative output voltage at up  
to 24W. The PT6640 is packaged in  
a 14-Pin SIP (Single In-line Package)  
and is available in a surface-mount  
configuration.  
• Wide Input Voltage Range:  
+8V to +25V  
• Negative Output:  
–2.5V/4A to –15V/1.5A  
• Adjustable Output Voltage  
• 85% Efficiency  
• Remote Sense Capability
