  • Abstract
    A low-voltage synchronous buck converter has been designed and fabricated in a 0.5mum CMOS technology. The converter uses two charge conservation techniques to increase efficiency at light loads while still operating in PWM mode at a switching frequency of 3MHz. These techniques reduce IC power loss from 11.5mW to 8.9mW, a 22.7% reduction, for lload = 20mA and Vout = 1.8V.
