The design and simulation of the circuit, which is designed to drive a power mosfet with a 500v breakdown voltage and maximum ia operation current, is implemented. the circuit can be used as a pre - regulator for electronic ballast. the ic solution also provides a voltage - regulator with the functions such as undervoltage lockout, and overvoltage protection
設計目的是使電路作為電子鎮流器的前端變換器可以驅動耐壓為500v ，最大工作電流為1a的橫向功率mos ，對整流電路的直流輸出電壓進行穩壓，並實現過壓、欠壓保護，提高用電效率，經過理論分析使經校正後的功率因數達到0 . 95以上。
