PT8100 Series 40-A 3.3/5-V Input Programmable Integrated Switching Regulator SLTS157A (Revised 8/23/2002) Features - 40ADC Output Current - +3.3V or +5V Input - Low Output Voltages: 0.8V- 2.7V - High Efficiency - Programmable Output: (VRM patible 5-bit Codes) - Multiphase Topology - Output Remote Sense - Short-Circuit Protection - Thermal Shutdown - Standby On/Off Control - Space-Saving Package - Solderable Copper Case Description The PT8100 Excalibur™ power modules are a family of high-output, high-efficiency, fully integrated switching regulators (ISRs), housed in a solderable 31-pin space-saving copper package. Modules are available for operation from either a 3.3V or 5V nominal input bus voltage. Each provides up to 40A of output current at output voltages as low as 0.8V. The output voltage is programmable via a 5-bit input code. The PT8100 series incorporates a state-of-the-art, 2-phase, multiple power path topology. This extends the output current range while providing superior transient response and input current ripple performance. The modules are designed for highend puting and signal processing applications, both of which demand high output currents at low supply voltages. The modules have a number of standard Features to facilitate system integration. These include shortcircuit protection, thermal shutdown, standby (On/Off) control, and an output remote sense to pensate for voltage drop between the regulator and the load. In addition, the voltage programming codes are patible with Intel’s® VRM specifications.
