Part Number: LM3429 Tool/software: WEBENCH® Design Tools I am using LM3429 LED driver for my buck converter design. Input is 60V to 72V and Output is 48V.
I need to know maximum wattage i can go using LM3429 LED driver ?
I need to design for 100W. But…
Part Number: LM3429-Q1 Other Parts Discussed in Thread: LM3429 , TPS92692 Hello, I am having trouble designing LED Boost driver using LM3429. Since it is being used for automotive applications, the input voltage is 9 - 16V and the output current set to be…
Part Number: LM3429 Hello
Used LM3429 for automotive lighting. Have a problem. When the compensation capacitance is 220nf, the frequency will jitter. When the capacitance is 47nF, the frequency will slightly decrease with the input voltage.
Part Number: LM3429 Dear Sir,
My customer would use LM3429 to design a Buck-boost circuit LED Driver.
He saw LM3429 IS have different connect method(as red circle): MOSFET Drain side & MOSFET Source side_ current sense resistor.
Could you kindly help…
Part Number: LM3429 Hello,
this chip when one uses the appnote, delivers Heavy but short current spikes to the load.
When running at 12Vin that is not an issue since the pulses only come at abt 40kHz.
But when running it at 6.5V, which one appnote says…
Hi Zacharias,
Thanks for your patience here. We have resolved the simulations issues regarding LM3429 (Vin = 6V Vout = 24.5 (NS6W183: 7 LEDs in series, Iout= 0.8)). Please find startup snapshot below. The fix will be available on ti.com by mid of next…
Part Number: LM3429 we have a heat problem with the LM3429 when running
it with Vin from 7.2 to 6V. With 12V it is ok. I understand that, judging from the data sheet that both
the 12V and the lower range is outside guaranteed specs. I must therefore try…
Part Number: LM3429 Tool/software: WEBENCH® Design Tools Hello, I am designing a driver for LED CMT2890 (Vf=54V; I=3.3A) using LM3429. The input: + VIN=12V + Vled=54V; I=3.3A. => Iswitch~20A. I tried to use WEBENCH but the tool does not support my case.…
Part Number: LM3429 hi sir,
my customer use LM3429 to drive a 13.3 inch panel, now customer use a external PWM to Dimming , now customer wants to know what's MAX Frequency of PMW connected the pin 7(ndim),Tks.
