I need to develop a AM35x based SBC module, which will replace an existing ARM9 based module.
To maintain compatibility I have to supply this module with a 3.3V only.
I found several reference designs, but all are using PMIC controllers powered from input voltages from 5V or higher.
Is there a reference design available, which ensures the Power sequence requirements with a 3.3V only input ?
