PIN FUNCTION DESCRIPTION Pin No. Symbol Function Description, 7 IN INPUT Input Voltage Pins. These pins are connected to the Wall Adapoter (AC DC, Vbus..). A F 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 recommendation for the pin7). 2 GND POWER Ground 3 FLAG OUTPUT 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 CC must be added. (Minimum 0 k). 4, 5 OUT OUTPUT Output Voltage Pins. These pins follow IN pins when no fault is detected. The two OUT pins must be hardwired together. 6 EN INPUT 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.
