Part Number: LP8556
Hello,
There is an exposed thermal pad on the WDFN package of the LP8556SQ-E09/NOPB chip.
Should-it be connected to GND or should be left unconnected?
Regards.
Sylvain
Part Number: LP8556 the formula : (CURRENT/4095) × IMAX × 20,000 × 1.2 V / RISET
But the RISET could be 12k to 100k
When the RISET is 24k , the max current/CH is 50mA
When the RISET is 14k , Is the max current/CH up to 100mA ?? or up…
Part Number: LP8556 Hi team,
I just need check the BGA package data.
Do you know t he size of the part pointed by the red arrow in the figure below is the value of the BGA electrode diameter "D"?
Thanks

Hi Sir
The new project requires the use of RGB LEDs in a common anode configuration to control the brightness requirement (without color mixing functionality).
Is it possible to use the LP8556 to integrate multi-channel control for…

Part Number: LP8556 Hello,
Can you confirm the output voltage for LP8556? In the datasheet features this is listed as "7-V to 43-V". Further down the datasheet under Device Options Output voltage is listed for individual part numbers in smaller windows…
Part Number: LP8556 In our application, the input voltage will drop to 5.2V, so that will impact the UVLO threshole level, then output will be off then on(loop), and backlight is become flickering.
Then, we've tried to change UVLO_TH to 0, or change the…
