Part Number: LM3414HV Hi TI team,
I would like to clarify something about the EMI behavior of LM3414HV LED Driver.
Our system, including a LED Driver Board with LM3414HV, recently passed CISPR32 radiated emission test with a low level of margin. Now…
Part Number: LM3414HV Other Parts Discussed in Thread: LM3414 , TPS922050 Tool/software: Hi,
In the datasheet, it is mentioned that the LED current is 350mA to 1000mA.But in the Analog Dimming Control, it is mentioned that the minimum LED current is…
Part Number: LM3414HV Tool/software: I have 4 LM3414HV driving 4 colored LED strings.(RGBW). The current needs to be the same for all four.
Can I use a single RIADJ resistor and connect all the IADJ outputs together. If so would the calculation of RIADJ…
Part Number: LM3414HV Other Parts Discussed in Thread: TPS922052 , TPS922053 Tool/software: Hi Steven,
I hope you are well.
I have currently adapted the design with the LM3414HV IC and have had a PCB manufactured.
Please see circuit diagram below…
Part Number: LM3414HV Tool/software: Hi Steven,
The minimum inductor value calculation equation is incorrect on the datasheet.
Please see below screenshot:
VIN is 48V and not 35V as entered into the equation.
Can this please be amended and up…

Hi there,
I have followed the datasheet and prototyped the application circuit for an output current of 1A:
The LED panel I am using is:

The components I am…
Part Number: LM3414HV Other Parts Discussed in Thread: LM3414 , Hi,
Since the procurement of LM3414MR is not good, we are considering using LM3414HVMRX as an alternative product. When comparing the current values, it was confirmed that the LM3414HVMRX…
Part Number: LM3414HV Other Parts Discussed in Thread: LM3414 , TPS922052 , TPS922053 Hi,
about LM3414, on the datasheet i can read that thermal protection is 170°C, but in the absolute maximum rating, the Tj is 125°C
I think there is a mistake on…
Part Number: LM3414HV I have a design which uses multiple LM3414HV channels, but they all need to be set to the same LED current, and that needs to be adjustable.
Can a common variable resistor or a resistor ladder with DIP switches, be used to feed…
Part Number: LM3414HV I can measure a significant LED current overshoot during power up. The peak current is about 2.5A/50µs (Iset = 1A) with Vin=24V and a single LED (Vf=3V) for load.
As the number of LED is increased the peak current is reduced, similarly…
