Part Number: TPS61181 Dear TI team : Here is a RD engineer from Taiwan. I have a question about dimming with TPS61181. As the datasheet said, TPS61181 already has DCTRL pin to dim with PWM. However, there is a document called "Analog Dimming with the…
Other Parts Discussed in Thread: TPS61181 , TLC59116 Hi ,
I will implement TPS61181 to drive 40 pieces of dual color (red and green)LED.
The maximum forward voltage of one piece LED is 3.7 volt.
There are two methods below,
1. 8 series using IFB1…
I think it somehow sounds like you've had TPS61180 mounted instead of TPS61181... it has exactly the described "one-takes-all-down" behaviour...

Other Parts Discussed in Thread: TPS61181 Hi all,
I am newbie in driver porting.
I would like to use TPS61181 as my LCD-TFT touch controller on iMX6 DL platform.
I would like to know if I can download the software driver of TPS61181 from TI website…
Hello,
My customer has aquestion about TP61181A.
Could you teach me about question.
It is written in IFB Pin Unused of data sheet, and the GND connection or open.
However, the level of the output in Vo due to the difference in treatment of unused…
Other Parts Discussed in Thread: TPS61181 Hi,
Is there any sequence requiremnet between VBAT, EN and PWM at TPS61181 Power ON? If yes, what is the reqreuirement?
And is it OK to connect EN and PWM to Supply Voltage on TPS61181 board design?
Thanks…
Other Parts Discussed in Thread: TPS61181 We have a product using the TPS61181 to run four LED strings in a 5" display product. I saw one of them on broadcast TV last Sunday, and the 220Hz PWM backlight modulation is strobing very badly with the TV cameras…
What type of dimming, PWM or analog do you prefer?
If you want precise matching of the LED current per string, then I suggest one of the TPS61181/2 or TPS61183 with 3 of the strings disabled. Using those parts, you will need to apply a separate 5V…
Hi !
i am using the TPS61181 - QFN - and i have promlems to activate it !
i using the TPS61181 to activate LCD backlight - 8 LEDs for one string and total 3 strings -each string need 20 mA -> Total 60mA
i designed as the application note recommandded…
