... OFF OFF 2 Duty Cycle The typical maximum duty cycle of the MIC23060 is 80%. Efficiency Considerations Efficiency is defined as the amount of useful output power, divided by the amount of power supplied. Maintaining high efficiency serves two purposes. It reduces power dissipation in the power supply, simplifying thermal design considerations, and it reduces current consumption for battery powered applications ...

... MIC23060 during light load currents by only switching when it is needed. As the load current increases, the MIC23060 goes into continuous conduction mode (CCM) and switches at a frequency centred at 4MHz. The equation to calculate the load when the MIC23060 goes into continuous conduction mode may be approximated by the following formula: . This ...
