Abstract
A switched power converter includes a switchable power stage for generating an output voltage according to a switching signal and an input voltage via a switching element. The switching signal is generated by a multi-mode controller. The multi-mode controller controls a digital control path for generating a pulse width modulation switching signal and a constant-on-time control path for generating a constant-on-time switching signal. The switching signal for controlling the switching element is generated in the digital control path when the multi-mode controller is run in a high load mode. The switching signal is generated in the constant-on-time control path when the multi-mode controller is run in a light load mode.
