32 AMP HIGH-PERFORMANCE  
“SLEDGE HAMMER” PROGRAMMABLE ISR  
Revised 7/15/98  
The PT7772 is a new series of  
can be easily programmed from 1.3V  
high-performance, 32 Amp Integrated  
Switching Regulators (ISRs) housed in  
a 27-pin SIP package. The 32A capa-  
bility allows easy  
integration of the latest high-speed,  
low-voltage µPs, ASICs, DSPs, and  
bus drivers into existing 3.3V systems.  
The output voltage of the PT7772  
to 2.05V with a 4-bit input compatible  
with Intels Pentium Pro Processor. A  
differential remote sense is also pro-  
vided which automatically compensates  
for any voltage drop from the ISR  
to the load.  
2400µF of output capacitance  
are required for proper operation.

(1) ISR-will operate down to no load with reduced specifications. Please note that this product is not short-circuit protected.  
(2) The minimum input voltage is 3.1V or Vout+1.2V, whichever is greater.  
Output Capacitors: The PT7772 series requires a minimum output capacitance of 2400µF for proper operation. Do not use Oscon type capacitors.  
The maximum allowable output capacitance is 30,000µF.  
Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 32ADC with a typical value of 1µH.  
The input capacitance must be rated for a minimum of 2.6Arms of ripple current. For transient or dynamic load applications, additional  
capacitance may be required.
