Detect condition Voltage of FB pin is greater than the threshold.
OVP Change mode Operation disable without latch off
Recovery condition Voltage of FB pin is less than the threshold (auto recovery).
Current of SW pin is greater than the threshold with counting 64 cycles × 750 [kHz] and
SW
Detect condition
the output voltage of VO_BT is less than 85% compared with the target voltage.
OCP Change mode Operation mode changes from PWM mode to PFM mode.
Current of SW pin is less than the threshold and input edge signal from low level to high
