Typical Application

LTC1706-19 Typical Application


The LTC®1706-19 is a precision, digitally programmed, resistive ladder which adjusts the output of any 1.19V referenced regulator. Depending on the state of the four VID inputs, an output voltage between 1.3V and 2V is programmed in 50mV increments. The LTC1706-19 is designed specifically to program an entire family of Linear Technology DC/DC converters in full compliance with the Intel Mobile VID specification. The LTC1706-19 programs the following Linear Technology DC/DC converter products: LTC1433, LTC1434, LTC1435, LTC1435A, LTC1436, LTC1437, LTC1438, LTC1439, LTC1538-AUX, LTC1539, LTC1624 and LTC1625. (Consult factory for future compatible DC/DC converter products.)
