Note: Fault–H occurs when the output voltage level is over the OVP threshold, pass transistor in the converter is shorted when
input voltage is applied, or when a difference between input to output voltage exceeds 2.4 volts with the input voltage only at 3.3V
nominal and not at 5V nominal.
Enable L: This input signal is used to enable the output
of the converter when activated (active Low). The
signal is referenced to output side (-Sense) or GND.
