Voltage Programming Accuracy
Built-In 40k Pull-Up Resistors on Program Inputs
Available in MSOP-10 Packaging
The LTC
®
1706-85 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 1.05V and 1.825V
is programmed in 25mV increments.
The LTC1706-85 is designed specifically to program an
entire family of Linear Technology DC/DC converters in full
compliance with the Intel Voltage Regulator Module (VRM)
8.5 specification.
The LTC1706-85 programs the following Linear Technol-
ogy DC/DC converter products: LTC1622, LTC1628,
LTC1629, LTC1702, LTC1735, LTC1735-1, LTC1772,
LTC1773, LTC1778, LTC1929, LTC3728 and LTC3729.
Consult factory for additional DC/DC converter products
compatible with the LTC1706-85.
