Note 3: This parameter is tested in a feedback loop that servos V
reference voltage with the V
Note 4: This specification represents the maximum voltage on V
switching (GATE pin) is guaranteed to be off. The nominal value of V
where switching turns off is 0.7V.

Note 5: The LTC3824 typically enters Burst Mode operation when the load
is less than one third the current limit. If minimum on-time is violated,
cycle skipping may occur at higher current levels.
