LBO Leakage Current
Power-OK Threshold
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.
2) The voltage at the LBI pin is below 0.1V (connected to GND) and V
OUT1
is below 92.5% of its nominal value.
