Single-Input Dual-Output (SIDO) Linear–Assisted DC/DC Converter

This article describes a single-input dual output(SIDO) linear-assisted DC/DC converter. Linear-assisted DC/DC converters are structures that allow to take advantages of the two classic alternatives in the design of power supply systems: voltage linear regulators and switching DC/DC converters. Thanks to the combination of a switching converter and two voltage linear regulators, the proposed SIDO converter provides two independent outputs with suitable load and line regulations. In the presented topology the SIDO linear-assisted DC/DC converter operates at the boundary of continuous conduction mode(CCM) and discontinuous conduction mode (DCM) with variable switching frequency
