VID Voltage Programmer for Intel VRM9.0/9.1

The LTC1706-82 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 1.10V and 1.85V is programmed in 25mV increments.

The LTC1706-82 is designed specifically to program ADI's entire family of DC/DC converters in full compliance with the Intel VRM9.0/9.1 specifications.

The LTC1706-82 programs the following ADI's DC/DC converters: LTC1628, LTC1629, LTC1702, LTC1735, LTC1735-1, LTC1929 and LTC3729.

For a compact VRM9.0/9.1 solution with up to 60A capability, see the LTC3732, a 3-phase synchronous controller with integrated 5-bit VID and MOSFET drivers.
