Abstract
A method of controlling a power supply includes detecting a transition of the power supply to discontinuous conduction mode (DCM), and locking an operating point of the power supply after detecting the transition. The operating point can be unlocked when a timer expires or when a feedback voltage slope exceeds a threshold.
