Due to high current levels and fast switching wave-
forms, proper PC board layout is essential. High-cur-
rent ground paths should be connected in a star
configuration to PGND. These traces should be wide to

stray inductance. All low-current ground paths should
be connected to GND. Place the input bypass capaci-
tor as close as possible to IN. See the MAX1640 EV kit
for layout example.
