Based on the careful analysis of switching power supply working principle and design parameters, a switching power supply based on TNY266P chip is presented. The key design is high frequency transformer circuit and optical coupling feedback circuit based on TL431. As the test results show our designed switching power supply has good performance in high effective, produced corrugation voltage stabilization and high volt-age adjustment rate.
