DN05109/D, High Efficiency DC-DC Converter Module

DN05109/D, Reference design describes a 12V, 15W flyback SMPS developed with the NCP12700BMTTXG controller. The SMPS operates from an input voltage range of 18 - 160 V while achieving greater than 85% full load efficiency. The SMPS was designed to operate in discontinuous conduction mode and implements secondary side synchronous rectification for improved efficiency, utilizing the NCP4308
