Abstract

This integrated single inductor dual-output boost DC/DC converter provides two independently regulated outputs with maximum efficiency at 83%. The converter operates in PWM and discontinuous mode at 500kHz using a 6.8uH inductor. Each output is time-multiplexed and regulated via current mode control. A drain-extended 0.13um technology allows backlight application up to 11V operation. The chip occupies 1.56 mm.
