Burst mode control and switched-capacitor converters losses

The feasibility of applying burst mode control in regulation of classical switched-capacitor converters is reevaluated. The results show that contrary to switched inductor based converters, this simple and easy to implement control has no efficiency advantage in terms of conduction losses over frequency modulation control when used to regulate classical switched-capacitor based converters. It is expected, however, that the burst mode could be viable for very low power applications in reducing biasing and housekeeping associated losses if reduced during the burst off time.
