The PT6500 series is Power Trends鈥?/div>
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.
