Abstract

A load dependent current-mode dead-times controller based on minimized duty cycle technique for DC-DC synchronous buck converters is proposed to achieve near -optimum dead times. This dead-times controller can dynamically adjust the dead times according to the variations of load. Experimental results demonstrate the validity of proposed circuit and power efficiency is raised about 1-5%. The chip size is 3.2 mm² in 0.35 μ CMOS process.
