Power Supply
3.3.1
Overview
The DC5V input power interface has overcurrent and inverse current
protection. The overcurrent limit is 2A.
The TI LDO power supply chip is used to step down voltage from 5V to
3.3V, 3.3V to 2.5V and 3.3V to 1.2V. The power supply can support up to
2A, which can meet the power demand of the development board.
