Part Number: LP8866-Q1 Hello,
In Hybrid mode, is the PMW phase shifted? Or phase shift is active only in Phase-shift PWM mode?
Thank you.

Hi Team
Customer would like to change the Switching frequency form 400Khz to 100Khz for improving the EMI issue.
According the datasheet SEPIC 100 kHz, the inductor need to use 22uH.
Do you know w hy the inductor value is different…

Part Number: LP8866S-Q1 Hi Team
Regarding the LP8866S switching frequency setting of RST_FSET PIN (number RB67), the current default is 400KHz.
Define 3.92K 1% switching frequency range 372KHz~428KHz Is it feasible to use 3.90K 1%?
Part Number: LP8866-Q1 Hi Team
There is a good news that we DIN LP8866!
Could you please help confirm the design and Schematic is ok? THX

Part Number: LP8866S-Q1 Hi All
In datasheet of LP8866S-Q1, the Dimming ratio for 152Hz IS 32000:1
and dimming resolution in 152Hz is 16-bit
I would like to know is there any relation between 32000:1 and 16 bit? and where is 32000 come from?
Looking…
