PIN DESCRIPTION
Pin 1 2 3 4,5 6 7 8 9 10,11 Function GND Input Inhibit + Vin + Vout + Sense Sync Parallel - Sense GND Output Description Return for input voltage source. Internally connected to pin 10,11. The converter is ON (Enable) when this pin is unconnected or the voltage applied is lower than 1.2V. The converter is OFF (Inhibit) for a control voltage in the range of 2 to 24V. DC Input voltage; recommended maximum voltage is 36V. External capacitor between pin 3 and pin 1 is mandatory; recommended value is 1000µF/50V for switching application. +12V output voltage. Senses the remote load high side. To be connected to pin 4,5 when remote sense is not used. Synchronization output. See figures 1,2,3,4. Take care to leave the pin open when is not used. Parallel output. See figures 1,2,3,4. Take care to leave the pin open when is not used. Senses the remote load return. To be connected to pin 10,11 when remote sense is not used. In parallel configuration, take care to connect all -S pins together (see figures 1,2,3,4). Return for output current path. Internally connected to pin 1.
