Product Overview

IRPLLNR5 is a reference design board which features IRS2168DPBF advanced PFC and ballast control IC. The PFC circuitry operates in critical conduction mode and provides high PF, low THD and DC bus regulation. It has protection from failure of a lamp to strike, filament failures, end of life protection, DC bus undervoltage reset as well as an automatic restart function. This board has a typical ballast output stage using current mode filament heating will result in excessive filament current during running. The output stage has therefore been configured for voltage mode filament heating using secondary windings off of the resonant inductor LRES. The active power factor correction section is a boost converter operating in critical 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.
  • High frequency operation
  • Lamp filament preheating
  • Lamp fault protection with auto restart after lamp replacement
  • Low AC line protection
  • Lamp end of life shutdown
  • High power factor, low total harmonic distortion
