1. The dynamic supply current is higher due to the gate charge delivered at the switching frequency. The Quiescent Current is measured

while the DC-DC Converter is not switching.

2. LBO goes low in startup mode as well as during normal operation if,

1) The voltage at the LBI pin is higher than LBI threshold.
