Fault Indication Pin. This pin allows an external system to detect a fault on the IN pins. The FLAG pin
goes low when input voltage exceeds OVLO threshold or drops below UVLO threshold. Since the
FLAG pin is open drain functionality, an external pull−up resistor to V
10 kW).
Enable Pin. The device enters in shutdown mode when this pin is tied to a high level. In this case the
output is disconnected from the input. To allow normal functionality, the EN pin shall be connected to
GND to a pull down or to a I/O pin. This pin does not have an impact on the fault detection.
Input Voltage Pins. These pins are connected to the Wall Adapoter (AC−DC, Vbus ..). A 1 mF low
ESR ceramic capacitor, or larger, must be connected between these pins and GND, as close as
possible to the DUT. The two IN pins must be connected together to power supply. (See PCB recom-
mendation for the pin7).
Ground
Output Voltage Pins. These pins follow IN pins when “no fault” is detected. The two OUT pins must
be hardwired together.
