Other Parts Discussed in Thread: LM3444 , LM3445 I want to drive 5 LED's of 1 watt each using AC supply of 230 v 50 HZ.
specification requirement:
(1) output 5 watt , 300 mamp of constant current
(2) Total harmonic distortion < 10%
While searching…
I found the above pdf document and went through it. In the circuit, I could not find the below mentioned components.
R8 R9 R10 R11 R13 R17 R33 R36 R37 R41 R44 C5 C6 C8 C27 C30
Please clarify if these components are not needed or something else.

Other Parts Discussed in Thread: TPS92411 Hello, I am interested in using TI's TPS92411 and TPS9210 in a AC direct LED circuit using 240v and noticed the excel calculators would not allow the use of the higher wattages such as 600 watts. Thankyou
Other Parts Discussed in Thread: UCC25600 Dear SIr,
Request you to provide gerber of PMP4288 based on UCC25600 along with the winding information for the board since we intend to localiise the manufacturing process, if thing go smooth, the quantities…
Other Parts Discussed in Thread: TPS92640 Hi,
Does TI has IC for Syncronous offline AC/DC LED driver?
I've found TPS92640/41 driver but as I understand from ABSOLUTE MAXIMUM RATINGS the voltage on the VIN, UDIM, SW pins shouldn't exceed 90V. Is it…
Hi
for a 25W LED application a flyback PFC stage is needed (even if isolation is not a requirement).
Dimming is needed, but not with Triac (just from a uController signal).
Does TI have suitable solution for this application? eventually ref des…
Dear All.
I started to design 230W AC/DC LED driver. And I found a good reference which is titled by "PMP4288".
Although that reference is targeted for LED application, there is no CC control (constant current).
The writer simply missed CC control…
Other Parts Discussed in Thread: TPS92411 Hi,
- what will the removal from the circuit of capacitors connected in parallel to the LEDs?;
- what will replace these capacitors on ceramic, which have a significantly lower capacity?
please answer info…
Hi All
I want to design 9watt to 20 watt constant current led driver with dimmable. But importantant specification are input range support up to 305VAC.
please suggest any suitable part from TI.
Thanks.

Alpesh.
Dear Irwin,
Thanks a lot for your support. We have successfully completed the design of 72W Driver using TPS92210.
We tested it for 2 Months under various conditions and the results are very good.
We used PQ3220 Tx. In the extreme Block conditions…
