PT6900 Series  
12 Watt 5V/3.3V Input  
Plus to Minus Voltage Converter  
SLTS041A  
(Revised 6/30/2000)  
• +5V/+3.3V Input Voltage  
• Negative Output  
• Remote Sense  
• Adjustable Output Voltage  
• 23-pin SIP Package  
The PT6900 is designed to supply  
regulated negative voltages for power-  
ing the latest ECL (-5.2V) and GaAs  
(-2.0V) ICs used in high-speed fiber  
optic communications. A 330µF elec-  
trolytic capacitor is required on the  
input and output for proper operation.  
Please note that this product is not  
short-circuit protected.  
The PT6900 is a series of high-  
performance ISRs, that provide plus to  
minus voltage conversion, up to 12 watt  
in a 23-pin SIP package.
