We examine the properties of a de-biased quantum dot in the Coulomb blockade regime. For voltages V that are large compared to the Kondo temperature T-K, the physics is governed by the scales V and gamma, where gamma similar toV/ln(2) (V/T-K) is the nonequilibrium decoherence rate induced by the voltage-driven current. Based on scaling arguments, self-consistent perturbation theory, and perturbative renormalization group, we argue that due to the large gamma the system can be described by renormalized perturbation theory in 1/ln(V/T-K) << 1. However, in certain variants of the Kondo problem., two-channel Kondo physics is induced by a large voltage V.
