A.
For most applications, FB1 and FB2 should be externally connected to resistor dividers as close as possible to the
device. For other implementations, refer to FB terminals connection discussion in the Application Information
section.
B.
If the SEQ terminal is floating at the input, VOUT2 powers up first
