UC3872: Alternative TI ballast controllers (without PFC) for ICB2FL03G replacement

Guru 12400 points
Part Number: UC3872


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:

  1. Among these devices, which would be suitable for fluorescent lamp inverter operation with AC line input (180–270 VAC rectified bus)?

  2. 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
