Part Number: LM3447 Other Parts Discussed in Thread: LM3406 Dears,
Could you please let me know the LM3447MTX/NOPB's tape and reel information?
I need the each sizes of the tape and reel packing.
Thank you.
Part Number: LM3447 Hi, we purchase the LM3447-A19-120VEVM and we modify to our need (new transformer and related part). We try to make it start but the IC start in 812ms fault at Vin 36Vac rms.
VCC is stable at 11.5V.
Vbias is around 14V.
COMP have triangle…
Part Number: LM3447-PAR-230VEVM I have bought LM3447-PAR-230VEVM. In the datasheet,
www.ti.com/.../sluua02.pdf
page 11, fig12, you show input current. But I have not obtained this current, The input voltage and current graph is in the following link…
Other Parts Discussed in Thread: LM3447 Hello, can i use the pin of INV to accept the opto-isolator feedback from the secondary output to achieve constant voltage output?
Thanks.

Other Parts Discussed in Thread: LM3445 , LM3447 Dear Sir,
I have read from the LM3445 datasheet that the FLTR2 pin can be used for analog dimming input .
It is also possible to do analog dimming with the LM3447 like the LM3445 ?
Thanks !
Nathan
Part Number: LM3447 Dear TI Team,
We have developed a solution on LM3447 Led driver ic with dimming option using Design calc excel sheet for LM3447.
But had a query to ask regarding this ic.
if we connect the dimmer in the circuit board, we are able…
hi sir ,
nice to contact again
remember me about the design 50watt led driver using lm3447
we were face a big problem about the the TVS diode that it was heating and over come this problem by connecting series tvs diode
after finish our design we found…
Other Parts Discussed in Thread: LM3447 I need to know two parameters of LM3447, not described in the datasheet:
1) What current can source FLT1 pin w/o significant internal voltage drop (i.e. max 0.2V), and w/o significant impact on overall performance…
Other Parts Discussed in Thread: LM3447 I need an equation of control law that is provided by LM3447 - how duty cycle depends on voltage on INV input.
I didn't find this infomation in the datasheet. Please help me.
Other Parts Discussed in Thread: LM3447 Dear Sir ,
How are you ? I hope you are good also your work .
we use LM3447 to make 50 watt led driver . when connect the power .out put go up and down from 30 v to 40 v
i measured the volt on Vcc it go up and…
