PT 7716o = 1.075 to 1.85Volts  
PT 7744o = 20-A Booster *  
The PT7716 Excalibur™ power module  
is a 20-A integrated switching regulator  
(ISR) housed a 27-pin space-saving copper  
package. Operating from a 3.3V-input bus,  
the PT7716 produces a tightly regulated  
supply voltage that is programmable over  
the range, 1.075V to 1.85V. The output  
voltage is selected via a 5-bit code. The  
code adjusts the output voltage in steps  
of 25mV and is VRM 9.0 compatible.  
This regulator is ideally suited for  
applications that employ microprocessor  
and DSP products that require core supply  
voltages as low as 1.075V.
