LTC1706-81 - 5-Bit Desktop VID Voltage Programmer

The LTC®1706-81 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 1.3V and 3.5V is programmed in 50mV and 100mV increments.

The LTC1706-81 is designed specifically to program an entire family of Linear Technology DC/DC converters in full compliance with the Intel Desktop (VRM 8.4) VID specification.

The LTC1706-81 programs the following Linear Technology DC/DC converter products: LTC1622, LTC1628, LTC1629, LTC1702, LTC1735, LTC1735-1, LTC1772 and LTC1929. (Consult factory for future compatible DC/DC converter products.)

Features Programs Regulator Output Voltage Range from 1.3V to 2.05V in 50mV Steps and from 2.1V to 3.5V in 100mV Steps (VRM 8.4) Programs a Wide Range of Linear Technology DC/DC Converters with a 0.8V Reference Fully Compliant with the Intel Pentium® Processor Desktop VID Specification ±0.25% Accurate Output Voltage Built-In 40k Pull-Up Resistors on VID Inputs Available in MSOP-10 Package Typical Application
