Part Number: LP8863-Q1 Hello!
I am attempting to drive an LED string at near 900mA using the LP8863 in the following setup:
SEPIC mode with 24V input and 23.2V max output with RFB1=150k and RFB2=470k.
400 kHz switching frequency
33uH coupled inductor…

Hi,
I drive leds with the lp8863.
The power on the card is O.K and the SPI communication working.
The leds are flickering (all the…
Part Number: LP8863-Q1 Hi, Team
Hope you are doing well!
My customer is evaluating our LP8863-Q1 and has some questions about our device.
(1) What's the internal structure of SS_ADDRSEL Pin? Is there any Pull Down or Pull Up resistors?
(2) For input…
Part Number: LP8863-Q1 Other Parts Discussed in Thread: LP8864-Q1 , Hi team,
In LP8863-Q1 datasheet, you put the Rsense near the input ground. However, in LP8864-Q1 datasheet, you put it near the output ground. It makes me confused.
Is it ok to place it…
Part Number: LP8863-Q1 Hi team,
I see in datasheet it's required that typical rise/fall time of switching FET should be less than 10ns. My customer use FET with around 20ns. What's the impact?
Thanks.
Part Number: LP8863-Q1 Hi,
Any external diode Leakage Current limitation?
I see only recommendation on the Vf (forward voltage < 0.5 V) and the VR (The voltage rating of the output diode must be at least 25% higher than the output voltage level).
I…

8863, I found that when the input power runs out, the waveform on the startup gate is continuous and the input capacitor will not sound.
When I turn on 8863, I immediately disconnect it and then turn it on again. When I turn…
