resistance and to route heat away from the device. The

exposed paddle lowers the thermal resistance of the

package by providing a direct-heat conduction path

from the die to the printed circuit board (PCB). Connect

the exposed paddle to the GND plane directly under

the IC, but do not rely on EP for ground functions. For

good thermal dissipation, solder the exposed paddle to

the power ground plane. Refer to the MAX8822 evalua-

tion kit data sheet for an example PCB layout.
