Part Number: TPS61196 Dear Support,
I almost copied the TPS61196EVM to a new design. the design goal is to drive an UV-LED chain, total 14 LED with nominal Vf = 5V. that is about 70V. so set the R21 in attached schematic to 255K(74V).
set the R43 to…
Part Number: TPS61196 I have designed a board using the TPS61196 6 string 400mA WLED driver and copied the circuit from the TPS61196 EVM board. We have checked the board for all continuity and are seeing the expected values with no fault at all of the…
Part Number: TPS61196 Hi
Our product need to support to adjust LCM MAX brightness for different condition(indoor or outdoor).
For example,the brightness of LCM is 1000nits at outdoor and 800nits at indoor.
Could TPS61196 support dynamic adjust MAX current…
Part Number: TPS61196 Thank you for your time today.
We're looking to use TPS61196 in an application, and I'm having an issue getting the regulator to startup. To note, on both chips VDD hits ~6V when (simultaneously) enabled and PWM1-6 appear…
Part Number: TPS61196 Hello,
I am an FAE for a distributor that handles TI products. My customer asked me about IFB current accuracy. The datasheet specifies IFB accuracy at 130mA as shown below. However, the customer wants to set it to 90mA. What is the…
Part Number: TPS61196 Hello,
I am considering an LED driver with the following specifications. I think the TPS61196 would be a good fit, but will this device meet my specs? Also, this device seems to have no calculator tools. Are there any calculation tools…

Hi Team,
Our customer is using TPS61196PWPR to control 4 strings of WLEDs (15 series LED) with series voltage of 46.5V typical @ 80mA/string. Everytime he turns on the power supply, the strings of LED turn on randomly, sometimes one…
Part Number: TPS61196 Hi,
What is the difference between TPS61196 and TPS61196-Q1?
It seems that the recommended operating ambient temperature is different, but are there any other differences?
Best regards,
Part Number: TPS61196 Thank you for your time today. I've been looking over the various LED drivers without luck - is anyone aware of and/or could anyone recommend an equivalent part for the TPS61196 with 8 channels? The PWM must be able to be controlled…

Dear TIer,
I would like to discuss the dimming by PWM for TPS61196.
Why the VDS of the dimming FET clamping when the Dimming FET turn off? refer to the following figure.
LED string is simulation by E-Load.
