PT8120 Series 30-A 12-V Input Programmable Integrated Switching Regulator SLTS158B (Revised 6/6/2002) Features - Single Device: 30ADC - +12V-Input - High Efficiency: 92% @3.3V - Programmable Output: (VRM patible 5-bit Codes) - Multiphase Topology - Output Remote Sense - Over-Current Protection - Thermal Shutdown - Standby On/Off Control - Space-Saving Package - Solderable Copper Case Description The PT8120 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. These modules operate from a nominal input voltage of +12V to provide up to 30A of output current at output voltages as low as 0.8V. The output voltage is programmable via a 5-bit input code. The PT8120 family 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 PT8120 family is designed to power high-end puting and signal processing applications, all of which demand high output currents at low supply voltages. The modules have a number of Features to facilitate system integration. These include over-current protection, thermal shutdown, an on/off standby control, and an output remote sense to pensate for voltage drop between the regulator and the load. In addition, the voltage programming codes for the PT8121, PT8122, & PT8124 are patible with Intel’s® VRM specifications.
