Part Number: LM3429 Other Parts Discussed in Thread: LM3409 , (1) PSPICE for TI program complained about the "NC" pin, so I had to connect to the node between two 976k resistors where one is connects to Vin and the other to ground (0V).
Once past…
Part Number: LM3429 Hi all,
I am a noobie in electronics design . I tried to design IR led Driver circuit with LM3429 . I took reference of example 8.2.2 Buck-Boost Application - 6 LED s at 1 A.
The device is not turning on . In this reference the the cathode…
Part Number: LM3429 Hi Experts,
Our customer has a concern about LM3429, he needs to know the efficiency and LED output current of this IC for Vin=8 to 36V and Vo=9.2V ILED=0.7A.
He also mentioned that there is no efficiency for Vo=8 to 10V with ILED…
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 controlled…
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 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
Vin: …
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…
Part Number: LM3429 Hi Team, I've made a LED buck-boost (BB) driver based on LM3429. It's for automotive lighting, so Vin = 9-14.5 V, LED string consist of 10 white leds. Vout is about 30V, Iout=1.3A. All components were calculated according to LM3429…
Part Number: LM3429 Other Parts Discussed in Thread: TPS92692 , TPS92691 Hi,
I am planning to do a design using the LM3429 and I don't want to use the analog dim function as it could lead to potential problems. I am considering to use two sets of RSNS…
