Description  
Ordering Information  
PT7671o = 1.3 to 3.5 Volts  
The PT7671 Excalibur™ high perfor-  
mance integrated switching regulator  
(ISR) is rated for up to 30 A. Housed in  
a 27-pin, space-saving, solderable cop-  
per package, the PT7671 delivers a  
higher output current than many mod-  
ules of similar size. This makes it an  
ideal choice where both a high output  
current and minimum board space are  
desirable. The PT7671 operates from a  
+5-V input bus and produces a tightly  
regulated output voltage that is pro-  
grammable over the range, 1.3 V to  
3.5 V. The output voltage is selected via  
5-bit input code, which is compatible  
with VRM specifications.  
The PT7671 is most suitable for  
powering high-end DSP, ASIC, and  
microprocessor circuits that require  
core or I/O logic supply voltages as low  
as 1.3 V.  
Other features include output short-  
circuit and over-temperature protection,  
a standby control, and a differential  
remote sense to compensate for voltage  
drop between the regulator and load.  
The PT7671 is also pin compatible  
with the 20-A rated PT7711.
