ISL8107
Locate the ISL8107 within 2 to 3 inches of the MOSFET, Q1,
(1 inch or less for 500kHz or higher operation). The circuit
traces for the MOSFETs’ gate and source connections from
the ISL8107 must be sized to handle up to 2A peak current.
Minimize any leakage current paths on the ENSS pin and
locate the capacitor, C
internal current source is only 33µA. Provide local V
decoupling between VCC and GND pins. Locate the
capacitor, C
the phase node.
