Part Number: LM3429 Other Parts Discussed in Thread: TPS92692 , TPS92691 Hi All,
It is a very simple question. I am doing an application using the LM3429 and I need to use the analog dimming functionality. I would like to use the method 1 to dim the…
Part Number: LM3429 Dear TI Support and Expert,
I am looking for a LED driver like LM3429, the chip support up to 5A, we use Max to 3.5A. but the evaluation board was default set to Max 1A.
From the data sheet, it mentioned that the current is…
Part Number: LM3429-Q1 Other Parts Discussed in Thread: LM3429 I'm designig a new project where the project needs operate in a wide input voltage range (from 9 to 60V).
How can I proceed with the loop compensation in this case? Is LM3429 able to operate…
Part Number: LM3429 Hi,
I have a question about LM3429 IC. Are there any examples of circuits with LM3429 as constant current regulator (without any leds)? Does it differs strongly from circuits for leds? Or I just have to use zero params (Vout, Rout…
Part Number: LM3429 Greetings,
I'm having a difficult time with LM3429 as a driver IC. It's supposed to work properly between 9 to 16 V, and it does. Except when I lower the voltage to below 6 V, since when the circuit first turns off, it doesn't turn…
Part Number: LM3429 I have I problem with over temperature LM3429 and switching MOSFET and system work with efficiency above 80%. Maximal efficiency is only on 300khz (Rt=82k) on more high frequency, efficiency is very low.
Topology: buck-boost

Part Number: LM3429 Other Parts Discussed in Thread: TPS92691 Hi sir, I need an analog dimming implement for LED load board current regulate with NTC resistor. Looks LM3429 datasheet scetion7.3.5 result A higher resistance value will source more current…
Part Number: LM3429-Q1 Other Parts Discussed in Thread: LM3429 , Hi,
Is there any difference in the design or assembly line between the ICs LM3429-Q1 and LM3429 (non-automotive)?
Both PNs have the same datasheet. Is the difference just the AEC qualification…
Hi Naveen,
The LM3429 is a controller so it can be designed to provide 100W output since the main power loss on the converter is the external power FET. There will still be power dissipation on the LM3429 for driving the external FET so care still need…
