I'm confused on whether SS_CTRL should have been tied to VIN if I use a C_FF cap? I need a ramp time greater than 0.2ms and chose SS_CTRL = GND and C_NR/SS = 10nF for a ramp time of approximately 1ms. But I also wanted to reduce the output noise to very low levels so I added a 10nF C_FF. Can I use the following configuration below? The layout example showed SS_CTRL tied to ground with a cap for C_NR/SS and C_FF.
SS_CTRL = GND
C_NR/SS = 10nF
C_FF = 10nF
