• Manufacturer Part Number: ISL8225MIRZ-T
• Description: ISL8225M Series 20 Vin 1.5 Mhz Dual 15 A Single 30 A Step-Down Power Module
• Manufacturer: Intersil

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.
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
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.
