1 / 8 page For technical support and more information, see inside back cover or visit www.ti.com/powertrends Standard Application Cin = Required 2000µF electrolytic (1) CL = Optional capacitance at load (1) R1 = Required 10k pull-up resistor when using the PWRGD* signal. The PWRGD* output is low when the output voltage is within specifications. 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 PT8000 VID4 – VID0 34 33 32 31 30 PROGRAMMING PINS VID0 VID1 VID2 VID3 VID4 C IN + V IN GND V IN x8 x10 x10 V OUT GND L O A D C L + V OUT GND 25 + REMOTE SENSE – REMOTE SENSE 20 STBY* 22 PWRGD* V DD 21 PWRGD* +SNS –SNS STBY Q 1 Description The PT8000 series is a 60 A high- performance, 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 Ordering Information PT8001 o = 1.3 to 3.5 Volts PT8002 o = 1.075 to 1.850 Volts For dimensions and PC board layout, see Package Styles 1600, 1610 and 1615 PT Series Suffix (PT1234X) Case/Pin Configuration Vertical Through-Hole N Horizontal Through-Hole A Horizontal Surface Mount C integration. Output short-circuit protection and over-temperature shutdown enables these modules to survive any load fault. Two self- diagnosotic 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. PT8000—5V 60 Amp High-Performance Programmable ISR • Output Tracking Feature • Over-Temp Shutdown • Power Good & OV Flag • Low-Profile Package • Solderable Copper Case • “Current Booster” Compatible SLTS135A (Revised 4/5/2001) |
