The LTC1706-81 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 ADI DC/DC converters in full compliance with the Intel Desktop (VRM 8.4) VID specification.
The LTC1706-81 programs the following Analog Devices DC/DC converter products: LTC1622, LTC1628, LTC1629, LTC1702, LTC1735, LTC1735-1, LTC1772 and LTC1929. (Consult factory for future compatible DC/DC converter products.)
Applications
- Intel Pentium II and III Processor Power Supply
- AMD Athlon™ Processor Power Supply
- Workstations and Servers
- Large Memory Array Supply
