PT8000—5V 60 Amp High-Performance Programmable ISR SLTS135A (Revised 4/5/2001) Features • • • • 60A Output Current Multi-Phase Topology +5V Input 5-bit Programmable: 1.3V to 3.5V 1.075V to 1.850V • High Efficiency • Differential Remote Sense • Short Circuit Protection Ordering Information Description PT8001o = 1.3 to 3.5 Volts PT8002o = 1.075 to 1.850 Volts The PT8000 series is a 60 A highperformance, Integrated Switching Regulator (ISR) housed in a single low-profile 44-pin SIP package. Operating from an input voltage of +5V, the PT8000 series offers a state-of-the-art “Plug-in Power” solution for highly-integrated digital systems that demand high power supply currents at low voltages. The output voltage from these modules is programmable over a preset range via a 5-bit input. The PT8001 may be set from 1.3V to 3.5V, which is compatible with Intel’s Pentium Pro® µ-processors. The output voltage of the PT8002 is programmable from 1.075V to 1.85V. The PT8000 series incorporates many features to facilitate system PT Series Suffix (PT1234X) Case/Pin Configuration N A Horizontal Surface Mount C For dimensions and PC board layout, see Package Styles 1600, 1610 and 1615 Vertical Through-Hole Horizontal Through-Hole • • • • • • Output Tracking Feature Over-Temp Shutdown Power Good & OV Flag Low-Profile Package Solderable Copper Case “Current Booster” Compatible integration. Output short-circuit protection and over-temperature shutdown enables these modules to survive any load fault. Two selfdiagnosotic signals, “Power Good” (PWRGD*) and “Over-Voltage Flag” (OVF*) are provided. And a unique tracking feature allows the output to be synchronized to a master ramp voltage during power-up. Other features include a standby input, and a differential remote sense to compensate for voltage drop between the ISR and load. A low ESR capacitance of 2000µF is required at the input for proper operation.

(3) See Safe Operating Area curves or contact the factory to determine the appropriate derating. Input Filter: To facilitate the high output fast trqansient performance, a high quality 2,000µF input capacitor(s) is required for the PT8000 series. Use either tantalum or Oscon® type capacitors with a maximum ESR (equivalent series resistance) of 20mΩ.
