Part Number: LM2755 Hello, we are locking for the soldering prodile of this part. We soldered several samples and one of 11 are not correct soldered.
Unfortunately we do not found this soldering profile in the datasheet.
Many thanks Michael Cerbe
Other Parts Discussed in Thread: LM2755 , LP5562 , LP5562EVM I am writing a driver for multiple LM2755 in parallel on the I2C bus. I have a basic driver working by controlling the High level from 1-31 and when off, setting the General purpose Bits 0, 1,…
Part Number: LM2755 Hi, ETE support
I want to know the upper limit of case temperature on LM2755. In the data sheet, I could find the information of junction temperature only (and that relation of ambient temperature).
Could you tell me the upper limit…
Part Number: LM2755 Hi Team,
On the LM2755 datasheet we mention that the shutdown supply current of 5uA typ can be achieved when EN1 = EN2 = EN3 = 0. Does HWEN accomplish this as well as Bits 0,1,2 in the General purpose register (0x10)?
Thank you, …
Part Number: LM2755 Hello ,
We did not see a specification on the SYNC pin logic level thresholds. It was unclear in the datasheet what is the logic level high threshold. Is it 0.65 * VIO or is it 1.23V like the hardware enable pin? Please let me know…
Part Number: LM2755 Hi,
My customer has the following questions...
A few details on the setup first: • Iset to 15mA with a 16.6k resistor. • The current is being measured through a single red LED. • A 50ohm series resistor is placed in the path…

Hi,
My customer would like to know: for the charge pump caps can you comment if 0.1uF would work instead of 0.47uF? Specifically GRM033R61A104ME15.
Thanks,

Part Number: LM2755 Hi,
My customer would like a schematic review for the following:
We plan to interface the LED driver with our MCU using 1.8V I2C logic. Can you verify that my schematic connections are correct? 1. SDA and SCL lines are pulled up to…
