In this paper, we demonstrate 20A operation and high switching frequency 980 KHz of single chip DC/DC converter. The fabricated chip consists of the digitally control block, the low on-resistance MOSFET switches and the drivers. The chip adopted low impedance metal bump technology. The on resistance of Nch MOSFET is 4.3m (@drain current=10A, gate voltage=5V… CONTINUE READING
