Abstract
A fluorescent lamp driver circuit is provided. The fluorescent lamp driver circuit uses reversed current detecting signal to achieve feedback control and circuit protection so as to simplify the driver circuit and reduces the number of the required electronic components. The driver circuit needs a single control unit to control the whole circuit, which not only reduces cost, but also simplifies circuit design.
