Abstract
A delay applied to a turn-on time for a high side switch in a switch mode power converter prevents oscillation between continuous and discontinuous conduction modes under light load conditions. The delay equalizes turn-on time for a high side switch with respect to continuous and discontinuous modes, so that turn-on time is not treated differently between the different modes. The delay value can be set for be equivalent to a propagation delay through a driver for a low side switch, in addition to a turn-off time for the low side switch. The addition of the delay element tends to maintain the switch mode power converter in a discontinuous mode under light load conditions and avoids oscillation between discontinuous and continuous conduction modes.
