LED Driver ICs Forum Discussions

Stop and tail multiplex LED lights. The LED fishing net structure meets n-1. The LED current is 55mA and the duty cycle is 8.3%. T1 is 12 LED lamps and T2 is 15 LED lamps.

Using LITIX ™ Basic + series， Is there a recommended combination scheme for basic + series products with the lowest cost?For example, two TLD2141-3EP？

Hi,

I have designed my Power Supply with XDPL8219 and sent it to TAC to get support but They said "We do not have the capacity to check individual designs directly. "

We do not have any local FAE to help us. 

We need your support to resolve the problem here, I have just changed little things when compare with your sample design. (https://www.infineon.com/dgdl/Infineon-Engineering_report_REF-XDPL8219-U40W-ApplicationNotes-v01_01-EN.pdf?fileId=5546d462737c45b901739fceff16729b)

We can get voltage at the HV and VCC pin, but there is no voltage on GD pin to start MOSFET.

I have double-checked the schematic compared with your sample design but can not see anything. 

I have no more time to finish and start real production for a project.

Please check the attached files. 

Thank you very much

Omer

Hi,

I'm evaluating a LED driver solution for a client and have been trying for some time now in vein to get my TLD5542-1HIPOW_EVAL board talking to the config wizard via the uIO board. The stick shows up in device manager as "HID-Compliant-Vendor-Defined-Device" but the Config Wizzard just will not recognise it saying no device connected. Is there anything I'm missing or I can do otherwise to debug the issue? I'm well stuck.

I've just been following the guide for the eval board here:

https://www.infineon.com/dgdl/Infineon-TLD5542-1HIPOW_EVAL-UserManual-v01_00-EN.pdf?fileId=5546d46277fc743901784c5c16613499

By the way I had another problem which is that config wizard is not available on the Mac version of Infineon Toolbox however this is not documented anywhere and took me some time to figure out. Just thought I'd offer this as feedback.

Thanks for your time.

John.

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

Hello,

Can We use power supply that was made with XDPL8219 as snubberless using an extra capacitor and IPD95R450P7ATMA1 or IPD95R750P7ATMA1?

950V Mos: https://www.infineon.com/dgdl/Infineon-ApplicationNote_MOSFET_CoolMOS_P7_950V-AN-v01_00-EN.pdf?fileId=5546d46264a8de7e0164cca95f2938dd

If that method is possible, what are the advantages and disadvantages of using snubberless method?

Please check the attached schematic

Hello, Im looking into Infineons LED lighting soultions. I have a Question about what is an LED driver? I hear the term often and it seems like its in differnet context every time. Is a driver the broad term used to cover circuitry that powers LEDs? Or is it an IC that is used regulate current to help keep LEDs effecient? 

Hi,

We want to design 54V 1.2A power supply with XDPL8219.

I have checked the design guide, but I am not professional, so Is there any excel document or tool to calculate values of the component and transformer when based on our output value?

Thank you very much

Waiting for your reply
