Hi Emmett,
I don't mean to cast aspersions on your design; is there a reason you are constructing your own controller, versus using a device designed for this? TI has a couple of simple devices that appear would "drop in" for what is shown. The TL4242…
Part Number: LMZ14202H Other Parts Discussed in Thread: LMZ14201H , , TPS51622 , TL4242-Q1 I am using the LMZ14201H and LMZ142010H as a power supply in an LED lamp circuit.
The LED string current is controlled by a linear driver at constant current…
Oh, that will be a problem for 2 reasons. 1) the maximum Vin of the TPS61166 is 10V and 2) the TPS61166 is a boost converter. So, when Vin is > Vout, it will be unable to step down the input and regulate the current.
For your input voltage range, I…
Part Number: TPS92630-Q1 Other Parts Discussed in Thread: TL4242-Q1 , TPS92612-Q1 , TPS92611-Q1 , Hello all,
I am looking for a linear constant current/sink/source for a string of white LEDs, and I have noticed the TPS92630-Q1 which could do it for…
Sonoki-san,
Besides TL4242-Q1, TPS92630-Q1 is also LED driver which can drive three channels led loads. And the max current of each load can reach 150mA. If there are not so many loads, TL4242-Q1 should be a suitable choice.

The TPS61086 datasheet has good information that will help you understand the available output current at different input voltages and currents. Please refer to figure 8 and go through the datasheet design procedure. Output current is much less than the…
Hi Jacky,
Sorry for the late reply. If you don't mind we can send mail to me to discuss it in detail as it will be faster. For TPS92630-Q1, it can't report each channel fault separately unless customer uses one TPS92630-Q1 for one LED. But this will…
Madhu,
For the PSice model, go to the Product Folder page for this device: http://www.ti.com/product/tl4242 , scroll down to the Models section, click on the model you want .
For the DDPAK footprint, go to the -Q1 PF page: http://www.ti.com/product…
Other Parts Discussed in Thread: TLC59731 , TLC5916 , TLC5922 Hi,
I'm trying to find the best driver for my application but I haven't be able to decide. I think I can get some help choosing here.
I need to control the brightness of 4 groups of dual…
I couldn't see any exact pin2pin part, but similar (in functionality)...
have a look at the http://www.ti.com/product/tps75105 and http://www.ti.com/product/tl4242
