Description  
Ordering Information  
PT7681o = 2 to 3.5 Volts  
The PT7681 Excalibur™ is a high  
performance integrated switching regu-  
lator (ISR), which is housed in a 27-pin  
space-saving solderable copper pack-  
age. Operating from a +5V input source,  
the PT7681 delivers up to 30A of out-  
put current over the adjustable output  
voltage range of 2V to 3.5V. The high  
output current and relatively small size  
makes the PT7681 suitable for power-  
ing high-end DSP, microprocessor,  
and ASIC circuits requiring core or I/O  
logic supply voltages as low as 2V. The  
output voltage is programmable via a  
4-bit input code.  
A special feature of the PT7681 is  
the Margin Up and Margin Down  
controls. These controls provide a  
convenient method for testing the  
load circuit over its supply voltage  
margins during production and quali-  
fication test programs.  
Other features include output short-  
circuit and over-temperature protection,  
a standby on/off control, and a differ-  
ential remote sense to compensate for  
voltage drop between the regulator and  
load.
