Layout Recommendation
The layout is a very important converter design step to make
sure the designed converter works well. For ISL8011 buck
converter, the power loop is composed of the output inductor
L, the output capacitor C
OUT
, Phase pin and PGND pin. It is
necessary to make the power loop as small as possible. In
order to make the output voltage regulate well and avoid the
noise coupling from the power loop, SGND pin should be
connected with PGND pin at the terminals of the load.
The heat of the IC is mainly dissipated through the thermal
pad. Maximizing the copper area connected to the thermal
pad is preferable. In addition, a solid ground plane is helpful
for EMI performance.
