Description

The LTC^®1706-82 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 an entire family of Linear Technology DC/DC converters in full compliance with the Intel Desktop VID specification.

The LTC1706-82 programs the following Linear Technology DC/DC converter products: LTC1622, LTC1628,LTC1629, LTC1702, LTC1735, LTC1735-1, LTC1772 and LTC1929.
