DESCRIPTIO
The LTC
resistive ladder which adjusts the output of any 0.6V
referenced regulator. Depending on the state of the five
VID inputs, an output voltage between 0.8V and 1.55V is
programmed in 25mV increments.
The LTC1706-61 is designed specifically to program
an entire family of Linear Technology DC/DC converters
with on board 0.6V references.
The LTC1706-61 programs the following Linear
Technology DC/DC converter products: LTC1629-6,
LTC3714, LTC3731 and LTC3778. (Consult factory for
additional DC/DC converter products.)
