7.3.1 Fixed-Frequency DCS-Control Topology
Figure 7-1 shows a simplified block diagram of the fixed-frequency DCS-Control topology used in the TPS6287x
devices. This topology is comprised of an inner emulated current loop, a middle direct feedback loop, and an
outer voltage-regulating loop. More details on this topology can be found in SLYT846.
