Note 1: The MAX686 requires a supply voltage at V CC = V DD between +2.7V and +5.5V; however, the voltage that supplies the
inductor can vary from +0.8V to +27.5V, depending on circuit operating conditions.
Note 2: The DAC output is set to its midpoint value at power-on.
Note 3: The DAC setting is guaranteed to remain valid as long as V CC is greater than the V CC DAC Reset Threshold.
Note 4: Specifications to -40°C are guaranteed by design, not production tested.
