Part Number:TPS65311-Q1
Hello,
I am considering using a TPS65311-Q1 for my PMIC but I have some questions on its capability. I have an FPGA-based standalone design with +24V input and need to create 5 voltages: +5V, +3.3V, +1.8V, +1.2V, +1.0V. The part has an SPI interface, but this application is standalone. By my read of the datasheet the SPI interface provides mostly error status.My main concern is on supply sequencing. Figure 24 on p. 32 shows the sequencing, but how is it controlled? Do I have to pick which voltages go on which regulator to get the sequencing I need? How is sequencing controlled? If the SPI interface is needed, can I set the values there and will they be retained after power cycling?
