Philips Semiconductors Product specification Electronic ballast controller circuit NE5565 DESCRIPTION The Electronic Ballast controller chip has been designed in a bipolar process. It is housed in a 20-lead dual-in-line plastic package. The control chip contains the equivalent of two (2) switched mode power supply control circuits. The first SMPS controller is a DC-to-DC converter operating in the discontinuous current conduction mode. It is used as a PFC in the ballast system to provide a DC voltage step-up function, good AC power factor, low AC current harmonic distortion, and circuit protection against some types of AC voltage transients. The PFC uses pulse width modulation to control the power transfer with an external MOS power transistor.
