sure the designed converter works well, especially under the high
current high switching frequency condition.
For ISL9104, ISL9104A, the power loop is composed of the
output inductor L, the output capacitor C OUT , the SW pin and the
PGND pin. It is necessary to make the power loop as small as
possible and the connecting traces among them should be
direct, short and wide; the same type of traces should be used to
connect the VIN pin, the input capacitor C IN and its ground.
The switching node of the converter, the SW pin, and the traces
connected to this node are very noisy, so keep the voltage
feedback trace and other noise sensitive traces away from these
noisy traces.
The input capacitor should be placed as close as possible to the
VIN pin. The ground of the input and output capacitors should be
connected as close as possible as well. In addition, a solid ground
plane is helpful for EMI performance.
