What does the larger PFET help with? The latest version of the board looks like this: The foregoing information relates to product sold on, or after, the date shown below. I am electronic engineer and I have worked over 6 years on embedded systems. Your project is really interesting to me and i can do your project correctly.

Texas Instruments LM3409HVEVAL/NOPB, LED Driver Evaluation Board for LM3409HV

Please enter a message. I hope a cooperation with you. I am looking to Hire Work. The i2c version will have 12 bit resolution steps vs 8 bit steps from a standard pwm microcontroller, will use true analog dimming and lm3409uv use only 2 interface pins for up to 8 drivers per i2c bus. Sign up using Facebook.

The schematic is basically the reference design plus a few small additions for dividing 5V into what the driver expects for analog dimming useful for arduino and similar other controllers. As always, open source and all files can be found here: Save this item to a new parts list.

Here is the schematic: We will complete within 10 days for schematic, layout and gerber out. Looking to make some money?

Quite a few changes have gone in. The two are basically the same DAC, but one has external addressing, while the other has external reference voltage. MElizabethp Hello my name is Maria I am an electronic engineer, I lm3409hb like to design this PCB for you, I have plenty of experience working with electronic and electric designs squematic and PCB layoutsprogramming microcontro More.

Hi, I read your project description. Choosing a high current ripple results in a high peak current which requires a inductor with a high saturation current. Flux and thin solder make life easy when you deal with SMD components! Hi Very interesting for your job description! Want to use a colour 3. What does all this mean? And this is a time-lapse of me populating a board. For analog dimming, all components are required and the outer two pairs of pins need to be lm3409hb on the 4 pin header.


Let’s discuss the details. It means that with current availability, you can put 8 drivers with MCP or 4 drivers with MCP on a single i2c bus.

However I was able to find only the first 4. My intent is to understand how to calculate the values lm33409hv the components needed for my specific application. Thanks in advance Martin. In your case the input voltage 42V and output load LED’s are fixed.

Thank you for your feedback. I actually have an i2c version ready as well. We have reviewed your input.
