Using ICB2FL03G as a ballast controller and dimming a 500W UV lamp

[KamiZ]

I am trying to replace the obsolete ballast controller IR21592IC and UCC2818 (PFC IC) with ICB2FL03G to turn ON and dim a 500W UV lamp. Using mains power, I am using UCC2818A IC to implement PFC boost converter and storing the voltage in a 220uF/450V electrolytic capacitor. Then I am using a half bridge circuit and UBA2014 to drive it and using a series resonant network, turn on a 500W ballast lamp (C3500).

I am looking for a reference design for this application which required dimming the lamp. we have a production quantity of more than 10000 boards per year.

This is critical and I don't have much time to make this work, any help is truly appreciated.

Thanks, Kamal

Hi Kamal,

I am discussing internally to check if we can get the reference design.

Meanwhile you can start working with the ICBFL03G Ballast IC. This IC has an integrated PFC and Half Bridge Stage. It has dimming capabilities as well.

You will find application notes and more details on the IC from this product page:

Hi Kamal,

Please refer to the attached document for reference designs of a dimmable fluoroscent lamps.
The reference design is by using a ICBFL02G IC, but same can be ported to ICBFL03G as well.

Hi Aliasghar,

Thank you for your detailed answer and sorry for my late response. I will use the provided application note and let you if it works.
