| Abstract: | At present, the application of switching mode power supply is becoming increasingly popular and is develo-ping to high efficiency, energy saving, security, environment protection and small size. Based on the LT3573, an isolated flyback DC- DC converter circuit is designed. Without optocoupler devices and the third winding, a stable voltage output can be obtained. The circuit is optimized and necessary simulation experiments are carried out. Then the reasonableness and reliability of the application circuit is verified by simulation results. |
