In this paper, a wide input range multiple output flyback switch-mode power supply (SMPS) with its design aspects is presented. The implemented SMPS is intended to be used in various applications in industry requiring low power and operating under wide input voltage fluctuations. The SMPS is designed using TOPSwitch off-line switched integrated circuit and includes line protection, input filter, rectifier, switching control, output rectification and feedback circuitries. A 5 Watt prototype has been manufactured and is validated through measurements. Experimental results obtained from evaluation tests demonstrate distinct features like wide input range, multiple regulated output voltages, isolation and high efficiency. Technology challenges for the full integration of the presented SMPS are briefly discussed.
