1. A method comprising:

  • detecting a start-up condition of a load, wherein (i) detecting a start-up condition comprises detecting a load voltage below a predetermined voltage threshold level and (ii) a start-up condition includes when the load voltage is below the predetermined voltage threshold level during a normal operation of a switching power converter;

    upon detecting the start-up condition;

    causing the switching power converter to provide an amount of charge to the load at a rate in accordance with a start-up mode until reaching an energy-indicating threshold;

    determining if the energy-indicating threshold has been reached; and

    when the energy-indicating threshold has been reached, causing the switching power converter to (i) decrease the amount of charge provided to the load relative to the charge provided to the load during the start-up mode and (ii) operate in a distinct post-start-up-mode.
