5-Bit VID Voltage Programmer for AMD Opteron CPUs

The LTC1706-61 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 0.8V and 1.55V is programmed in 25mV increments.

The LTC1706-61 is designed specifically to program an entire family of ADI DC/DC converters with on board 0.6V references.

The LTC1706-61 programs the following Analog Devices DC/DC converter products: LTC1629-6, LTC3714, LTC3731 and LTC3778. (Consult factory for additional DC/DC converter products.)
