Sub:Request for Ballast IC for 11W UV-C Disinfection Lamp Design

Dear Texas Instruments Team,

We are in the process of designing a UV-C disinfection lamp with an 11W rating, and we are currently searching for a suitable ballast IC to efficiently drive the lamp. Specifically, we are looking for an integrated circuit from TI that can be used in our design.

Could you please recommend the appropriate ballast IC from Texas Instruments that is compatible with our 11W UV-C disinfection lamp? The lamp operates on [insert voltage and current details], and we need an efficient and reliable solution for power conversion.

If you have any reference designs, evaluation modules, or additional information related to driving UV-C lamps, that would be greatly appreciated.

Thank you for your support, and I look forward to your recommendations.

Regards,

Sathiya

    Sathiya,

    The system requirement is not clear. Please share the spec so we can recommend a part.

    Hi Ning Tan, 

    sorry form my delay reply,

    As part of our ongoing design, we have planned to use TUV 11W FAM/10X25BOX and Philips lighting. To support this, we intend to implement an onboard ballast solution for effective power management and optimal lighting control.

    Could you please assist in identifying and recommending a suitable Power Management Integrated Circuit (PMIC) for lighting applications, along with a compatible Ballast Controller Chip? We would also require a reference design to facilitate smooth integration into our system.

    Looking forward to your suggestions and any additional insights on potential solutions.

    Regards,

    Sathiya

    Sathiya,

    We need specific system requirements. e.g. Vin, Vout, Pout, Isolated topology? PFC features? etc.

    Sounds to me you need a single stage flyback to convert AC input from the grid to a 34V DC output. If so, you can consider TPS92210, UCC28051, and UCC2881x. Here is a reference design: https://www.ti.com/tool/PMP4484

    Hi Ning Tan,

    Below our requirements Details.

    Ballast Req

    Vin = 230V-240V,

    Line Frequency 50Hz to 60Hz

    Input Frequency 50Hz to 60H

    Light Details (TUV 11W IN FAM/10X25BOX)

    Power Consumption 11.5W.

    Voltage (Nom) 34V

    Lamp Current (Nom) 0.4 A

    Design Parameter Requirement/Explanation
    Input Voltage (Vin) 230-240V AC, 50/60 Hz
    Output Voltage (Vout) Typically low-voltage DC or high-frequency AC to drive the lamp (varies with lamp wattage)
    Output Power (Pout) Output power should match the lamp wattage (e.g.,11W 16W Ensure power conversion efficiency is ≥ 90-96%
    Topology Isolated topology, typically Flyback Converter or Buck-Boost Converter, to provide electrical isolation and safe operation
    Power Factor Correction (PFC) Active PFC with a power factor ≥ 0.98 to improve energy efficiency and reduce harmonic distortion
    Efficiency High efficiency (≥ 90-96%) to minimize energy loss and reduce heating in components
    Current Control Constant Current Regulation for flicker-free and stable lamp operation
    Power Losses Minimize losses in components like transformers, capacitors, and diodes
    Electromagnetic Interference (EMI) Mitigation Use EMI filtering components (e.g., capacitors, inductors) to meet EMI standards (e.g., CISPR 15)
    Thermal Management Ensure proper thermal dissipation; include thermal protection (e.g., thermal shutdown circuits) for safe operation within -10°C to +50°C
    Overcurrent Protection Protection circuit to prevent damage from overcurrent or short circuits
    Ripple Current Minimize ripple current to prevent lamp performance degradation
    Startup Characteristics Soft start feature to reduce inrush current and prevent damage to the ballast or lamp
    Load Regulation Stable output current regardless of input voltage variations or lamp type
    End-of-Life Features Design for safe lamp end-of-life handling (e.g., protection against runaway current)
    Electromagnetic Compatibility (EMC) Comply with EMC standards (e.g., EN 55015, FCC Part 15) to prevent interference with other electronic devices
    Power Consumption Minimize idle power consumption in standby mode for energy savings
    Operating Temperature Ensure the system can operate within a temperature range of -10°C to +50°C without risk of failure
    Voltage and Current Regulation Ensure tight regulation of output voltage and current to prevent fluctuating light output

    Sathiya

    This existing ref is the closest to your need: https://www.ti.com/tool/PMP4484

    >90% efficiency and >0.98 PF at 16W output will be hard to meet with single stage flyback. You can consider PFC + Flyback two stage solution but your cost will go up.

    Hi

    We’ve been using Philips TUV TL double-ended UVC lamps for our application, but it looks like the PMP4484 ballast isn’t suitable for our requirements. As you know, these lamps are based on traditional UVC technology (not LED), and we need a ballast specifically designed for these lamps.

    we used Light: (https://www.lighting.philips.co.in/prof/special-lamps/purification-water-and-air-/water/special-lamps/purification-water-and-air-/surface/tuv-tl-mini/928002204021_EU/product)

    Please contact your local FAE for ballast controller recommendation. 

    If you are interested in something like this, I will need to transfer you to a different group

    Hi Ning Tan,

    Thank you for your suggestion. Could you please share the contact details of the local FAE (Field Application Engineer) for ballast controller recommendations in the Chennai, Bangalore, or Coimbatore areas?

    Your help in connecting us with the right person would be much appreciated.

    Regards,

    Sathiya

    I already let the FAE know. You can also contact your leadership team to get our FAE contact. We have a team for your company.

    I cannot share their email here since it is a public forum.

    Best,

    Ning
