Description
The IR2166 Demo Board is a high efficiency, high power factor, fixed output electronic ballast designed
for driving rapid start fluorescent lamp types. The design contains an EMI filter, active power factor
correction and a ballast control circuit using the IR2166. This demo board is intended to ease 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.

Functional Description
Overview
The IR2166 Demo Board consists of an EMI filter, 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 types. The ballast control section also
provides the necessary circuitry to perform lamp fault detection, shutdown and auto-restart.
