operational voltage diode-ored between the
converter output (12 V) and input voltages. The
converter turns-on typically at 6.7 V. Once
energized, the output voltage supplies power to the
IC when the battery voltage is below
(approximately) 11.5 V. The decreasing V
UVLO voltage depends on load current as well as
