Abstract:
Pulse width modulation (PWM) techniques have been limited to 1 to 2 MHz by the switching speeds of currently available power switches. This limitation has been overcome by high speed (<2 nanosecond) switching with improved 1 /spl mu/m PMOS transistors. These devices have been incorporated in a 5 MHz, PWM buck power stage that has demonstrated good efficiency (>85%) and very high power density (500 W/in/sup 3/ versus state-of-the-art 100 W/in/sup 3/).
