PT6500 Series
8 Amp 5V/3.3V Input Adjustable ISR
with Short-Circuit Protection
SLTS034A
(Revised 8/23/2000)
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 a high perfor-
mance +3.1 to 6V input, 8 Amp, 14-Pin
SIP (Single In-line-Package) Inte-
grated Switching Regulator (ISR).
This ISR allows the 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 PT6502 (1.5V) provides the low
terminating voltages required by BTL/
Futurebus+, CTT, HP, and GTL Buses
from existing 3.3V or 5V power rails.
Ordering Information
