Dear All,

Please teach us setting of Device Control Pin of TPS2543.

When customer use DCP_Auto Mode, the setting of each CTL Pin is follows.

(CTL1,CTL2,CTL3)=(0,1,1)

(CTL1,CTL2,CTL3)=(0,0,1)

Please teach difference between (0,1,1) and (0,1,1).

    Refer to Table 2. Truth Tabel, you can find there are 4 DCP_Auto

    (1) CTL1, CTL2, CTL3, ILIM_SEL=0010

    (2) CTL1, CTL2, CTL3, ILIM_SEL=0011

    (3) CTL1, CTL2, CTL3, ILIM_SEL=0110

    (4) CTL1, CTL2, CTL3, ILIM_SEL=0111
