The major demand for portable electronics devicessuch as pagers, laptops, cellular phones etc. Single inputmultiple output (SIMO) converter will be proposed to givedifferent supply voltages while keep up prolong battery life. Asingle-discharge (SDC) control scheme is introduce to simplifythe Single inductor multiple output design, attain to low crossregulation, and to support board range of loads with decentefficiency of power. A Single discharge control single inputmultiple output buck converter with 4 outputs composed ofcomparators, phased-locked loop, finite state machine (FSM)controller, and an output stage. In addition to the basic switchingfunctions, the FSM controller provides a state skipping feature toallow no-load regulation. Single input multiple output converteris available for less cost and used for maintaining long batterylife and they are growing in vast range with rich feature portableelectronic device. The design of converter is designed for limitedrange for prolonged battery life. The SIMO converters are usedfor the reduction of cost and switching losses, hence improvesystem efficiency. In our study, we proposed buck convertertopology with single input of 24v and multiple output of 12v and5v. The 12v voltage is used for electric vehicles. In electricvehicles it is used in horns and headlights. 5v voltage is used forsmall signal and stability analysis. The simulated conversionefficiency for peak power is 86% the power ranging for output is50 to 300mW. The ICs exhibit has a low measured peakefficiency of 73% and cross regulation of 0.24 mV/mA becauseof parasitic bond wire resistance. The proposed system issimulated in MATLAB/Simulink software.
