nn Available in a 10-Lead (3mm Г— 2mm) DFN Package The LTCВ®7106 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. …
