The PT7681 ExcaliburTM is a high performance integrated switching regulator (ISR), which is housed in a 27-pin space-saving solderable copper package. Operating from a +5V input source, the PT7681 delivers up to 30A of output current over the adjustable output voltage range of 2V to 3.5V. The high output current and relatively small size makes the PT7681 suitable for powering high-end DSP, microprocessor, and ASIC circuits requiring core or I/O logic supply voltages as low as 2V. The output voltage is programmable via a 4-bit input code.
