Abstract:A kind of single-ended fly-back switching power supply.The power supply accurate outputs two channels DC voltages of +15V and -15V, its method of engineering design is brought forward according to the quality of TOP204, and its peripheral circuits are analyzed and discussed in terms of requirements and characteristics of power detection system. At last the performance of the power supply is verified through experiments.
