Features  
age. The 10A capability allows easy integration of  
the latest high-speed, low-voltage µPs and bus  
drivers into existing 5V systems.  
• Single-Device: +5V input  
• 5-bit Programmable:  
1.3V to 3.5V@10A  
The output voltage of the PT7600 is easily  
programmed with a 5 bit input compatible with  
Intel’s Pentium II Processor from 1.3V to 3.5V.  
A differential remote sense is also provided which  
automatically compensates for any voltage drop  
from the ISR to the load.  
• High Efficiency  
• Input Voltage Range:  
4.5V to 5.5V  
• Differential Remote Sense  
• 27-pin SIP Package  
1200µF of output capacitance are required for  
proper operation.  
The PT7600 is a new series of high-  
performance, 10 Amp Integrated Switching

* ISR-will operate down to no load with reduced specifications. Please note that this product is not short-circuit protected.  
** The minimum input voltage is 4.5V or V +1.2V, whichever is greater.

*** See SOA curves.  
Output Capacitors: The PT7600 series requires a minimum output capacitance of 1200µF for proper operation. Do not use Oscon type capacitors.The maximum allowable  
output capacitance is 7,500µF. See Capacitor Application Note.  
Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 10ADC with a typical value of 1µH. The input capacitance must be rated for  
a minimum of 1.0 Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
