(Note 4) Note 1: The MAX686 requires a supply voltage at VCC = VDD 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 VCC is greater than the VCC DAC Reset Threshold. Note 4: Specifications to -40°C are guaranteed by design, not production tested.
