Abstract
A switching mode power converter circuit is disclosed, comprising a first high-side switch and a first low-side switch coupled in series between an input voltage level and a reference voltage level, a second high-side switch and a second low-side switch coupled in series between the input voltage level and the reference voltage level, and a control circuit for controlling switching operation of the first and second high-side switches and the first and second low-side switches. The first high-side switch has a larger on-state resistance than the second high-side switch and the first low-side switch has a larger on-state resistance than the second low-side switch. The control circuit is configured to, during an on-state of the first and second low-side switches, control the second low-side switch to switch to the off-state and control the first high-side switch to switch to the on-state, so that the first high-side switch and the first low-side switch are both in the on-state. The application further relates to a method of operating such switching mode power converter circuit.
