Description  
Ordering Information  
The PT8120 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. These modules  
operate from a nominal input voltage  
of +12V to provide up to 30A of  
output current at output voltages as  
low as 0.8V. The output voltage is  
programmable via a 5-bit input code.  
The PT8120 family 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 PT8120 family is designed  
to power high-end computing and  
signal processing applications, all of  
which demand high output currents  
at low supply voltages.  
The modules have a number of  
features to facilitate system integra-  
tion. These include over-current  
protection, thermal shutdown, an  
on/off standby control, and an output  
remote sense to compensate for  
voltage drop between the regulator  
and the load. In addition, the volt-  
age programming codes for the  
PT8121, PT8122, & PT8124 are  
compatible with Intels® VRM  
specifications.  
PT 8121r = 1.3V
