  We present an update on the phase diagram of two-color QCD from a chiral
effective model approach based on a quark-meson-diquark model using the
Functional Renormalization Group (FRG). We discuss the impact of perturbative
UV contributions, the inclusion of gauge field dynamics via a phenomenological
Polyakov loop potential, and the impact of matter backcoupling on the gauge
sector. The corresponding phase diagram including these effects is found to be
in qualitative agreement with recent lattice investigations.
