Description
The PT8120 Excaliburâ„¢ 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 computing 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 compensate for
voltage drop between the regulator and the load. In addition, the
voltage programming codes for the PT8121, PT8122, & PT8124 are compatible with...
