2.1.13 S1, S2, S3, S4, S5, S6 – IC Configuration (R2D Interface)

The output voltage is set according to Table 2-1 and Table 2-2. The configuration pins CFG1, CFG2, and CFG3 must not be left floating. Every CFG pin has 16 switches for the different resistor values, but only one switch at a time can be set to ON for each CFG pin. Turn ON the corresponding switches written in Table 2-1 and Table 2-2 V_O(2) is set by switch-blocks S1,S2, S4, and S5. V_O(1) is set by switch-blocks S3 and S6.

Example: V_O(2) (SEL = VO2) is set to 3.4 V and the current limit to unlimited. Set S1.1 to ON for CFG1, S5.1 to ON for CFG2, and S3.1 to ON to keep CFG3 from floating.
