Abstract:Multi-functional intelligent instruments are widely used in various industries, and the process of detection, display and control. The design is based on TOPSWITCH-2 chip design a five Roads output of multi-functional intelligent instrument for the single flyback switching power supply. The design uses the first method to supply single-chip switching power supply circuit TOPSWITCH based on a multi-channel AC-DC power output. The design is according to the characteristics of the single-chip switching power supply integrated chip and give the specific designing steps of the intelligent instrument switching power supply, at the same time ,introducing the design of high-frequency transformers、the choice of the main parameters and making a specific calculation on.
Keywords: TOPSWITCH;Multi-functional intelligent instrument,Flyback switching power supply ,AC-DC multi-output power
