In this study, the design of low voltage DC-DC converter with switching device having low on-resistance. The switching device with low on-resistance was designed to decrease conduction loss. The PWM control circuits was made of a saw-tooth generator, a band-gap reference circuit, an error amplifier and a comparator circuit as a block. DC-DC converter, based on the PWM control circuits and low on-resistance switching device, achieved the high efficiency closed to 94% at 450mA output current.
