15 AMP HIGH-PERFORMANCE  
“BIG HAMMER” PROGRAMMABLE ISR  
The PT7700 is a new series of high-  
performance, 15 Amp Integrated Switching  
Regulators (ISRs) housed in a 27-pin SIP  
package. The 15A capability allows easy  
integration of the latest high-speed, low-  
voltage µPs and bus drivers into existing 5V  
systems.  
The PT7700 series has been designed to  
work in parallel with one or more of the  
PT7749 - 15A current boosters for  
Two products are offered in the series  
with different output voltage ranges that are  
easily programmed with a 4 bit input  
compatible with Intel’s Pentium Pro  
Processor. A differential remote sense is  
also provided which automatically  
compensates for any voltage drop from the  
ISR to the load.  
An input filter and 1200µF 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 PT7700 series can be easily paralleled with one or more of the PT7749 slave modules to provide increased output current in increments of 15A.  
Please contact Power Trends for the appropriate application note.  
(3) The minimum input voltage is 4.5V or V +1.2V, whichever is greater.  
out  
Output Capacitors: The PT7700 series requires a minimum output capacitance of 1200µF for proper operation. To reduce ESR, Power Trends recommends using four 330µF  
electrolytic capacitors in parallel. Maximum allowable output capacitance is 15,000µF.  
Input Filter: An input filter is required for all applications. The input inductor must be sized to handle 15ADC with a typical value of 1µH. The input capacitance must be rated  
for 14Arms of ripple current. Power Trends recommends using four Sanyo OSCON style capacitors with a 3.5Arms ripple current rating in parallel (p/n 6SA330M).
