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.
