Irplcfl6revb: High Power Cfl Ballast Using The Ir2166

provides for high PF, low THD and DC Bus regulation. The IR2166 features include programmable preheat and run frequencies, programmable preheat time, programmable dead-time, programmable over-current protection and pro- grammable end-of-life protection. This demo board is intended to facilitate the evaluation of the IR2166 Ballast Control IC, demonstrate PCB layout techniques and serve as an aid in the development of production ballast’s using the International Rectifier IR2166. The IRPLCFL6 Demo Board consists of an EMI Filter input rectification, an active power factor correction section, a ballast control section and a resonant lamp output stage. The active power factor correction section is a boost converter operating in critical conduction mode, free-running frequency mode. The ballast control section provides frequency modulation control of a traditional RCL lamp resonant output circuit and is easily adaptable to a wide variety of lamp powers. The ballast control section also provides the necessary circuitry to perform lamp fault detection, shutdown and auto-restart. The schematics for IRPLCFL6 is shown in figure 5.1 and the Bill Of Materials with the components values is shown in table 5.2.
