8 AMP ADJUSTABLE ISR

WITH SHORT-CIRCUIT PROTECTION

• 8A Single Device Power

• Up to 90% efficiency (PT6501)

• Small SIP Footprint

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.

• 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

* ISR will operate down to no load with reduced specifications.

Note: The PT6500 Series requires a 330µF electrolytic or tantalum input and output capacitor for proper operation in all applications.
