5-Bit VID Voltage Programmer for Sun CPUs

The LTC1706-63 is a precision, digitally programmed, resistive ladder which adjusts the output of any 0.6V referenced regulator. Depending on the state of the five VID inputs, an output voltage between 1.025V and 1.4125V is programmed in 12.5mV increments.

The LTC1706-63 is designed specifically to program ADI's entire family of DC/DC converters with on board 0.6V references. Please see the related parts list at the end of the data sheet.

For a 2-phase synchronous controller with on-board LTC1706-63, see the LTC3819.
