(English Abstract)
Since the non-overlapping gate driver used in conventional DC-DC boost converters generates fixed dead-times, the converters suffer from the body-diode conduction loss or the charge-sharing loss. To reduce the efficiency degradation due to these losses, this paper presents a PWM DC-DC boost converter with adaptive dead-time control. In light loads, power switching is also employed to increase the efficiency. The designed DC-DC boost converter can thus achieve high efficiency at wide current range. The proposed DC-DC boost converter has 3.3V output from a 2.5V input with 0.18um technology. It operates at 500KHz and has a maximum power efficiency of 97.8%.
