Abstract
The present invention discloses an electronic ballast with dimming control from power line sensing for a fluorescent lamp, comprising: a line switching sensing circuit, used to generate a switching sensing signal by performing a voltage comparison operation on a DC voltage; an oscillating signal gating unit, used to gate an oscillating signal with a pulse signal to generate a gated oscillating signal, wherein the pulse width of the pulse signal is generated according to the switching sensing signal; and a non-overlapping driver, used to generate a high side driving signal and a low side driving signal according to the gated oscillating signal.
