Abstract :
A new on-chip current sensing circuit for the over-current protection of the electronic ballast is presented in this paper. The proposed scheme increases the sense accuracy and noise immunity over the full temperature range of the devices and can avoid fault over-current protection. Simulation results verify the accuracy of the on-chip current sensing circuit.
