Abstract :
A noninverting flyback converter using an integrated symmetrically-matched self-biased current sensor was fabricated in a 0.35μm CMOS process. It operates in pseudo-continuous conduction mode and employs a direct output current control scheme to achieve excellent line transient response. The converter switches at 1MHz with an input of 1.2V to 2V to give an output of 1.5V and delivers 250mA.
