LED Driver ICs Forum Discussions
Hello,
I am developing a 300W LED Driver 90V 3.25A.
Facing issue with following things
1. output voltage range requirement is 50-90V, currently it is 78-90V.
2. Output current keeps increasing after the load in CC mode like current starts from 3.15A and rises to 3.45A
3. while doing pilot lot many drivers found not working. IC is not getting start.

Show LessHi,
Good day.
We are third party programmer manufacturer.
Customer requires TLD1314EL for programming, and we need the programming guide for development.
Could you help to provide the programming guide to us for development?
Thank you.

Show LessI need to drive 2 types of leds with ILD8150
1. First LED was 20Vdc operating 7W LED.
And
2. Led 12W, 40Vdc
Please suggest the circuit for above two LEDs.
Dimming facility is not required.
Show LessI want to power a lamp with usb c (5V 2A).
Do I need to adjust the input voltage to power a LED (2,7V 65mA), or can I just power the IC with the provided 5V from the USB-C?

Hello. In the "Application note - Ballast IC Design for 54W UV-C Disinfection Lamp" on the Top and Bottom Views of the Demo Board one can spot component places for a presumably dc input? Silkscreened as 1-10V for a connector of sorts then traces towards what looks like a choke/transformer. These components I am referring to are all in the general area of the ac input. Can I ask for the purpose and perhaps the missing schematic?
Is that an alternative power source or an auxiliary regulated output for something?
Show LessAs I attempted to evaluate the REF_TW_ILD8150E_60V_1A and created my own led driver base from the mentioned development board, I discovered that the LM5013 was a dimmable led driver. However, I am now experiencing buzzing sounds between 10% and 15% of PWM pulse dimming; beyond 15%, the buzzing sounds will cease. I am currently working on a PoE lighting system. Do you have any suggestions about how to get rid of the noise?

Hello you absolute legends.
Are there 16v uses for ICB2FL03G?
For use with dual G4T5 tubes.
Is there a DC powered circuit in the resources area/kb that I could copy and use with the ICB2FL03G?
For a portable application.
Thank you for your input.

芯片未进行过otp烧录,想要先实现串口转USB与芯片之间的通信。操作是向DC_UPDATEA-update duty cycle shadow register写入16个0x01,通过串口调试助手发送的数据为55 81 21 16个01 7D,并没有接收到返回值。可以帮我看一下是哪边出了问题吗?uart直连can收发器的物理层在附件中#TLD7002-16ES
