Hi,
We are currently evaluating alternatives to the Infineon ICB2FL03G ballast controller.
In our case, PFC functionality is not required — we are only looking for a TI controller that can handle the inverter stage (resonant / half-bridge lamp driver).
From our research, the following TI devices may be possible candidates:
-
UC3872 family – Resonant ballast controller, ZVS operation for fluorescent/gas-discharge lamps
-
UCC3305 / UCC2305 – HID lamp controller ICs
-
UCC3975/76/77 – Controllers for piezoelectric transformer (PZT) backlight applications
We would like to confirm the following points:
-
Among these devices, which would be suitable for fluorescent lamp inverter operation with AC line input (180–270 VAC rectified bus)?
-
If there are more recent TI recommended devices for this application, could you please advise?
We appreciate your support and look forward to your feedback.
Best regards,
Conor
