Description  
Ordering Information  
The PT8100 Excalibur™ power  
modules are a family of high-output,  
high-efficiency, fully integrated  
switching regulators (ISRs), housed  
in a solderable 31-pin space-saving  
copper package. Modules are avail-  
able for operation from either a 3.3V  
or 5V nominal input bus voltage.  
Each provides up to 40A of output  
current at output voltages as low  
as 0.8V. The output voltage is pro-  
grammable via a 5-bit input code.  
The PT8100 series incorporates  
a state-of-the-art, 2-phase, multiple  
power path topology. This extends  
the output current range while pro-  
viding superior transient response  
and input current ripple performance.  
The modules are designed for high-  
end computing and signal processing  
applications, both of which demand  
high output currents at low supply  
voltages.  
The modules have a number of  
standard features to facilitate system  
integration. These include short-  
circuit protection, thermal shutdown,  
standby (On/Off) control, and an  
output remote sense to compensate  
for voltage drop between the regu-  
lator and the load. In addition, the  
voltage programming codes are  
compatible with Intels® VRM  
specifications.
