DN05036/D, 12V, Monolithic Off-line Power Supply With Primary Side Regulation (PSR) Design Note

DN05036/D, Design Note describes a very simple, primary side controlled, 10 watt, off-line flyback power supply using NCP1075 current mode controller (SO-223 package). The power supply design is intended for low power applications such as E-meters, white goods, instruments, and industrial equipment where an output voltage regulation of +/-5% over a load range of 5% to 100% is acceptable with a Vout of 12 volts or greater
