Description

The LTC1706-85 is a precision, digitally programmed resistive ladder which adjusts the output of any 0.8V-referenced regulator. Depending on the state of the five VID inputs, an output voltage between 1.05V and 1.825V is programmed in 25mV increments.The LTC1706-85 is designed specifically to program ADI's entire family of DC/DC converters in full compliance with the Intel Voltage Regulator Module (VRM) 8.5 specification.The LTC1706-85 programs the following ADI DC/DC converter products: LTC1622, LTC1628, LTC1629, LTC1702, LTC1735, LTC1735-1, LTC1772, LTC1773, LTC1778, LTC1929, LTC3728 and LTC3729.Consult factory for additional DC/DC converter products compatible with the LTC1706-85.ApplicationsServer/Desktop ComputersMultiprocessor Workstations and ServersMultiphase Processor Power Supply
