Product Details
The LTC7106 is a precision, PMBus controlled, bidirectional current digital-to-analog converter that adjusts the output voltage of any conventional VFB referenced regulator. The LTC7106 can work with the vast majority of power management controllers or regulators to enable digital control of the output voltage. Internal power-on reset circuitry keeps the DAC output current at zero (high impedance IDAC) until a valid write takes place. Features include a range bit for easy interfacing to almost any impedance resistor divider, and an open-drain GPO output for controlling the Run or Enable pin of the DC/DC regulator. For most applications, the current DAC error is significantly attenuated with proper design. See more detail about VOUT accuracy in the Applications Information section of this data sheet. The LTC7106 is supported by the ADI LTpowerPlay® development tool with graphical user interface (GUI).
