Part Number: LP8863-Q1 HI all,
I have a question regarding ISET specification.
I am doing the measurement of ISET PIN during the operating condition and got the result 1.37V. Please confirm which specification was correct. Because in datasheet it has…
Part Number: LP8863-Q1 Hi all
I have a question,
currently I am doing the measurement of LED0-5, In our design we seperate it to 2 Channel, CH1 = LED 0,1,2. CH2 = LED 3,4,5,
But the wave of both channel is different (Kindly see the picture)
Thank…
Part Number: LP8863-Q1 Hi,
R&D has some questions regarding the LP8863s LED Driver Currently R&D is verifying the LED Driver, and we use the I2C register to set the LED Driver, For the LED Output String, we use 6 Channels with Automatic Phase Shift…
Part Number: LP8863-Q1 Hi team,
When the LP8863 is used in SEPIC mode, the output voltage is up to 24V in the data sheet. Is it not supported if customers set the voltage to more than 24V by changing resistance?
If they use higher value (e.g. 27Vout)…
Part Number: LP8863-Q1 Hi all,
I read the datasheet about the LED Open and Short Logic, I Want to make sure some item,
Condition
Vheadroom Min = 0.55V
Vheadroom Max = 0.55+0.5V (Hysteris)
LED Short detection Threshold we set = 4.2V
Our LED0-5 Result…

Part Number: LP8863-Q1 Hi Team,
on customer behalf I have a question about the purpose of Vovpl and Vovph thresholds of LP8863.
What is the reason to have two additional thresholds for the FB pin ? Is it to protect against some input voltage transients…
Part Number: LP8863-Q1 Hi All
I have a question about Feedback resistor
I tried to find it from the datasheet but I cannot find it,
in LP8863, The RFB2 Recommendation for SEPIC design is 170kOhm,
I would like to know, how to get 170kOhm, I Tried to calculate…
Part Number: LP8863-Q1 Hello,
I would like to ask you a question about LP8863-Q1. (Question) Where is the Exposed Pad (DAP) connected to the internal circuit? The Pin Functions description states that it is connected to LED ground. Is it the red circle in…
