Two examples of typical startup behavior for the TPS7A78EVM-041 are shown below. Figure 4-1 showcases startup with the maximum rated output current of 30 mA. Figure 4-2 showcases startup and output curent of 70 mA. While the EVM has only been designed up to 30 mA, the second startup shows that, with proper configuration, the EVM can be utilized to cover the full current spectrum of the TPS7A78 device.
