Jared, We found that the LM3435 could work at 1.8V with a ~20 kOhm resistor when tested as the only device on an I2C bus. However, as we added additional I2C devices and a voltage translator, the LM3435 was unable to pull SDA low with a 20 kOhm pull-up…
Part Number: LM3435 Hello team,
Do we have a 2D drawing for the LM3435 part with dimensions/tolerances? Preferably in a PDF format. What we have found so far only gives nominal dimension values.
Best,

Hi Ives,
Thanks for your suggestion. Now we have a new problem about the efficiency. We measured the input voltage (VIN) is 4V, and the output voltage(Vout) is 7.2V, the LED current setting is max.109mA, but the LED voltage drop is only about 2.5V. Does…

Hi
We use LM3435 and confuse as same as previous inductance calculation.
So inductance fomula still suit for this part?
For example, as our setting I LED(max) would be set on 1000mA. What inductor in value should I put for our change…
Part Number: LM3435 I wanted to use LM3435 evaluation board for my project with raspberry pi.
There are some doubts that I wanted to clear.
1.) What are we using I2C protocol for here ? With PWM, we can easily control the LEDs, right ?
2.) Why is the…

Hi TI E2E
Before, I used the LM3435 as our Head Mount Display LED driver.
and the result is great, but in some rare case, such as the LED control is failed (I2C write the led…
Part Number: LM3435 Dear customer support staff,
The data sheet has the following description, and so is Figure 7.
"The LED current setting can be in the range of 0.5A up to 2A maximum."
I would like to set the current to a maximum of 0.2A…
Part Number: LM3435 Other Parts Discussed in Thread: TPS92641 Hi team,
My customer has project about HUD. They want use our RGB driver. There will be three lamp beads which need 3~4A supply current for each. And our RGB driver for example LM3435 only…
