title = "Dynamic bootstrap voltage technique for high efficiency buck converter in universal serial bus power device supplying system",
abstract = "For high power universal serial bus (USB) devices, the dynamic bootstrap voltage (DBV) technique is proposed to keep high efficiency over a wide load range, including light and heavy loads. Besides, the silicon area of power management of the system-on-a-chip (Soc) can be effectively reduced to 50% of conventional design with P-type high-side power MOSFET. The test chip fabricated in 0.25μm CMOS process shows 92% peak efficiency from 1mA to 1A. The maximum driving current is higher than 3A with 88 % efficiency. Compared to that without the DBV technique, the efficiency is improved about 28%.",
