Typical Application

LTC1706-61 Typical Application

Description

The LTC®1706-61 is a precision, digitally programmed, 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.)
