8A Single Device Power
Up to 90% efficiency (PT6501)
Small SIP Footprint
Standby Function
Internal Short Circuit Protection
Over-Temperature Protection
Adjustable Output Voltage
The PT6500 series is Power Trends’
new high performance +3.1 to 6V
input, 8 Amp, 14-Pin SIP (Single In-
line-Package) Integrated Switching
Regulator (ISR). This high-perfor-
mance ISR allows easy integration of
high-speed, low-voltage Pentium pro-
cessors and their support logic into
existing 3.3V or 5V systems without
redesigning the central power supply.
The high-performance PT6502 solves
the problem of providing the low ter-
minating voltages required by BTL/
Futurebus+, CTT, HP, and GTL Buses
from existing 3.3V or 5V power rails
without redesigning the central power
supply.

* ISR will operate down to no load with reduced specifications.
Note: The PT6500 Series requires a 330F electrolytic or tantalum input and output capacitor for proper operation in all applications.
