Enable for the DCDC1 converter.
PWM or PFM Mode jumper, default setting is PWM.
The output from the DCDC1 switching regulator with a max output current of 1.0A and a default voltage
setting of 2.7V.
The output from the DCDC2 switching regulator with a max output current of 0.8A and a default voltage
setting of 1.8V.
The output from the DCDC3 switching regulator with a max output current of 0.8A and a default voltage
setting of 1.3V.
The output from the low drop out regulator, VLDO1, which has a max output current of 200mA and a
default voltage setting of 1.8V.
The output from the low drop out regulator, VLDO2, which has a max output current of 200mA and a
default voltage setting of 1.8V.
The output from the VDD_ALIVE low drop out regulator with a max output current of 30mA and a default
voltage setting of 1.2V.
The PWRFAIL output will assert low when the PWRFAIL comparator indicates a low Vin
Enable for the VDD_ALIVE low dropout regulator.
The EVM comes from the factory with the following default settings on the jumpers.
