Design of Single Input Multiple Output Buck Converter with Light Load Efficiency

The major demand for portable electronics devices such as pagers, laptops, cellular phones etc. Single input multiple output (SIMO) converter will be proposed to give different supply voltages while keep up prolong battery life. A single-discharge (SDC) control scheme is introduce simplify the inductor design, attain low cross regulation, and support board range of loads with decent efficiency power. discharge single buck 4 outputs composed comparators, phased-locked loop, finite state machine (FSM) controller, an stage. In addition basic switching functions, FSM controller provides a skipping feature allow no-load regulation. available less cost used maintaining long life they are growing in vast rich electronic device. design designed limited prolonged SIMO converters reduction losses, hence improve system efficiency. our study, we topology 24v 12v 5v. voltage electric vehicles. vehicles it horns headlights. 5v small signal stability analysis. simulated conversion peak power 86% ranging 50 300mW. ICs exhibit has measured 73% regulation 0.24 mV/mA because parasitic bond wire resistance. MATLAB/Simulink software.
