LTC1706-81

5-Bit Desktop VID

Voltage Programmer

FEATURES

DESCRIPTIO

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

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 com-

patible DC/DC converter products.)
