PT7681

The PT7681 Excalibur™ 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.

A special feature of the PT7681 is the Margin Up and Margin Down controls. These controls provide a convenient method for testing the load circuit over its supply voltage margins during production and qualification test programs.

Other features include output shortcircuit and over-temperature protection, a standby on/off control, and a differential remote sense to compensate for voltage drop between the regulator and load.
