Pin-Out Information
Description
The PT6930 Excalibur series of 8-A
dual-output ISRs are designed to power
DSP ICs. Both output voltages are inde-
pendently adjustable with external resistors.
The second output may also be set to an
alternate lower bus voltage with a simple
pin strap. Internal power sequencing of
both outputs, during both power-up and
power-down, meets the requirements of
most DSP chipsets.
