AAT3680
Lithium-Ion Linear Battery Charge Controller
PCB Layout
For the best results, it is recommended to physi-
cally place the battery pack as close as possible to
the AAT3680's BAT pin. To minimize voltage drops
in the PCB, keep the high current carrying traces
adequately wide. For maximum power dissipation
in the pass transistor, it is critical to provide enough
copper to spread the heat. Refer to AAT3680
demo board PCB layout, see figures 6, 7 and 8
below.
