Part Number: LM3429 Tool/software: Hello, we are currently looking to design an LED driver circuit based on LM3429, with a total power of 1200W and an input voltage of 51V. We intend to adopt a boosting scheme to increase the voltage and thereby reduce…
Part Number: LM3429 Tool/software: Hi TI Team,
We are currently using the LM3429MH/NOPB LED driver in a design with the following configuration:
Input Voltage: 12V (up to 8A available)
LED Configuration: 20 LEDs in series (each with Vf …
Part Number: LM3429 Tool/software: Hi
I would like to confirm whether this device can support
A. 300W design with an input of 19V–30V, boosting to 48V output at a constant current of 5.9A ,Is this application feasible??
B. pin 7 (nDIM) be used…
Part Number: LM3429 Tool/software: Hello, I am using the LM3429 to design an LED driver circuit, but I encountered an issue where the LM3429 is not working. I am using a buck circuit with an input voltage of 51V, a current design of 50A, and a switching…
Part Number: LM3429 Tool/software: Hi TI team，
The user is encountering an EMC issue with an LM34299-based boost LED driver where electromagnetic emissions exceed limits by 5dB in the 410MHz-600MHz range when PWM dimming is at maximum brightness.Please…
Part Number: LM3429 Other Parts Discussed in Thread: LMH13000 Tool/software: Hi, advise a modern driver for a 6W Laser. I want to do engraving at home. Forward voltage of the diode is 5V so that the current can be adjusted from 1A to 5A. I want to power…
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…
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 that…
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…
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…
