9.3.17 Output Configurations (MODE, FB2)
9.3.17.1 Independent Dual-Output Operation
The LM25143 has two outputs that can operate independently. Both VOUT1 and VOUT2 can be set at 3.3 V or 5
V without installing external feedback resistors. Alternatively, set the output voltages between 0.6 V and 36 V
using external feedback resistors based on Equation 5. See Table 9-1 and Figure 9-8. Connect MODE directly to
AGND for independent outputs.

9.3.17.2 Single-Output Interleaved Operation
Connect the MODE to VDDA and FB2 to AGND to configure the LM25143 for interleaved operation. This
disables the channel 2 error amplifier and places it in a high impedance state. The controller is then in a
primary and secondary configuration. Connect COMP1 to COMP2 and SS1 to SS2. Connect FB1 to VDDA for a
