Fault Protection Characteristics
Functional Description
Overview
he IRPLDIM1 Demo Board consists of an EMI filter, an active power factor correction front end, a
ballast control section and a resonant lamp output stage. The active power factor correction section
is a boost converter operating in critical mode conduction, 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 pro-
vides the necessary circuitry to perform closed-loop dimming, lamp fault detection, shutdown and
auto-restart. All functional descriptions refer to the IRPLDIM1 schematic diagram.
