42 Watt Compact Fluorescent Ballast


Posted on Dec 16, 2012

The CFL-2 is an electronic ballast design for driving a 42 watt compact fluorescent lamp from a 120 or 230 volt AC line. The circuit was designed using the IR2156 Ballast Driver IC. The main features of the circuit are programmable frequency, preheat time, over-current threshold and dead time. A circuit board was designed and tested to verify reliable functionality under actual operating conditions.



Features * Programmable preheat frequency * Programmable preheat time * Programmable over-current threshold * Programmable run frequency * Programmable dead time Electrical Characteristics Parameter Value Input Power 42W Input Current (120V) 530m
