Hi , I'm using the TPS65910A device as Power Supply for AM335X CPU .
1. Is it ok not to use at all the 5V ouput (SW3)? I mean just leave the SW3 and FB3 pins floating ?
2. According to http://www.ti.com/lit/ug/swcu093b/swcu093b.pdf part of boot critical voltage rails are in "default off " . So how will I cause them to ON ? Is I2C management configuration after boot is necessary for this device ?
3.According to the same document above the default core voltage VDD_MPU is 1.1V , it is not enough for the turbo mode operation of CPU (1.26V) ,so the voltage must be tuned up after boot by CPU in order to run in turbo 750mhz mode ?
Thanks
