Power Supply
The AMIC110 ICE can be powered from a 5-V DC adapter. Do not hot plug the +5-V supply into
the AMIC ICE; follow the instructions in
for plugging and unplugging the power supply. The
+5-V input is converted into the required supply voltages using a PMIC.
The TPS650250RHBR PMIC (U7) provides the required voltages and currents for all power rails of the
AMIC110 processor (see
