NOTES:

10. CIN bulk capacitor is optional only for decoupling noise due to the long input cable. CIN2 and COUT1 ceramic capacitors are listed for one phase only.

Please double the capacitor quantity for dual-phase operations.

11. EN/FF resistor divider is tied directly to VIN. The resistors listed here are for two channels' EN/FF pins tied together. If the separate resistor divider is

used for each channel, the resistor value needs to be doubled.

12. MAX load current listed in the table is for conditions at +25°C and no air flow on a typical Intersil 4-layer evaluation board.
