Overview
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...
