Part Number: LM3406 Dear
We observed the internal structure of the material using an Acoustic Microscope and found the phenomenon of layering. Please refer to the image (marked A)
Could you please help check if this is a defective product?
Will it affect…
Part Number: LM3406HV Other Parts Discussed in Thread: TPS92515 Due thte unavailabily of the TPS92151 we are trying to cope this situation installing a 5 turn trimmer in parallel to the sensing resistor in order to pick up a portion of voltage and send…
Part Number: LM3406 Other Parts Discussed in Thread: TPS92641 , Hi,
Why do the calculations in the LM3406 for buck duty cycle not include the efficiency estimate as they do with the TPS92641? They look like similar switching topologies, so I could use to…
Part Number: LM3406 Other Parts Discussed in Thread: TPS92515 , LM3405 , LM3409 Hello,
I have a customer looking for a recommendation to drive a simple 3x3 white LED array. I did not find a lot of information on ti.com regarding how to drive basic white…
Part Number: LM3406 Other Parts Discussed in Thread: LM3409 , , TPS92515 , LM3402 I'm trying to develop an LED application that takes an input of 28V and outputs 25V/360mA. From my initial calculations in the datasheet, I've determined that a switching frequency…
Part Number: LM3406 Hello team,

Part Number: LM3406 Hi,
I would like to ask you a question about the LM3406. When checking the LED waveform while changing the VIN voltage, two types of LED waveforms are generated as shown in the figure below. This is the PWM Dimming waveform. Multiple…
Part Number: LM3406 Hi,
I am creating a circuit using the LM3406 device. I input an external PWM signal and adjust the brightness of the LED, but I would like to ask you about that PWM. I will attach the waveform. Yellow is the waveform of LED current. Green…
Part Number: LM3406 Dear expert,
My customer is using LM3406HV in lighting. Now they found two problems as below, and made some tests. Could you help to check will their solution have other problems?
