There are two voltage regulators:
3.3V/2A that is the main supply voltage for both the
iMX RT1062 OEM board
and the
iMX
OEM Carrier board
.
This is a buck dcdc regulator to minimize power dissipation. The regulator can be switched
on/off by control signal EXT_PWR_EN.
3.3V/25mA that is the secondary supply voltage that is "always on". It powers the
VDD_SNVS_IN supply input on the i.MX RT1062. Current consumption is typically very low
on this supply. This is a linear regulator.
The picture below illustrates the location of relevant jumpers and LEDs.
