PROJECT TITLE :

A Dynamic Bootstrap Voltage Technique for a High-Efficiency Buck Converter in a Universal Serial Bus Power Delivery Device

ABSTRACT:

The dynamic bootstrap voltage (DBV) technique is proposed to keep high efficiency over wide ranges of load currents for high-power universal serial bus devices. The silicon area of the embedded power management with the DBV technique in the system-on-a-chip will be effectively reduced to 50% of the traditional style with a P-sort high-side power MOSFET. Take a look at chips fabricated in zero.twenty five-μm CMOS process showed a ninety two% peak potency from 1 mA to one A. The utmost driving current was on top of 5 A, and therefore the efficiency was eighty eight%. Compared with the potency of the converter while not the DBV technique, the potency of the converter with DBV technique was improved by concerning 28%.
