Dear Community members,
In the TPS65910 Specification (SWCS046U), VIO, VDD1, VDD2 SMPS list the following statements (page20, page23, page25 accordingly)
"Discharge resistor for power-down sequence Rdis min 30 max 50 Ω"
While checking the 335x EVM board schematics, I could not find such "explicit" off-chip discharge resistors. So how could I deal with these statements?
And in "TPS65910Ax User's Guide For AM335x Processors" (swcu093C), the EEPROM setting of VDD3 is "VDD3 time slot OFF". So does it mean that VDD3 SMPS doesn't work by default? In my design, I don't need this boosted voltage output and can I use the following connections?
1. SW3 floating
2. VFB3 shorted to GND
Thanks in advance
