Fully Compliant with the Intel VRM9.0/9.1 VID
Specification
Programs Regulator Output Voltage from 1.10V to
1.85V in 25mV Steps
Programs an Entire Family of Linear Technology
DC/DC Converters
±0.25%
Accurate Voltage Divider
Built-In 40k Pull-Up Resistors on Program Inputs
Available in MSOP-10 Packaging
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 VRM9.0/9.1 specifications.
The LTC1706-82 programs the following Linear Technol-
ogy DC/DC converters: LTC1628, LTC1629, LTC1702,
LTC1735, LTC1735-1, LTC1929 and LTC3729.
For a compact VRM9.0/9.1 solution with up to 60A capa-
bility, see the LTC3732, a 3-phase synchronous controller
with integrated 5-bit VID and MOSFET drivers.
