Part Number: LP8866-Q1 Hi Expert:
I have two questions regarding the LP8866-Q1 SNVA964 Application note.
The first question is whether the Figure 7 (b) on page 5 depicts the spread spectrum disabled or spread spectrum enabled with ±3.3% variation? …
Part Number: LP8866-Q1 ZhiQian,
Customer short charge pump output to GND for over current test. But they didn't get interrupt. What is the possible reason?
Their all registers are in default value.
Thanks

Hi team,
Based on calculator tool of LP8866-Q1. if I use Dimming Frequency ≦4883Hz. "Might have audibale noise concern" this grid will show Yes.
So I searched the answer at datasheet…

1. For BSTOVPL fault, when FB voltage over 1.4V, device will trigger this fault and set BOOST_FAULT_STATUS resister, FET will turn off at the same time. when FB voltage less than VFB-OVPL, boost will restart.
Is BOOST_FAULT_STATUS…
Part Number: LP8866S-Q1 HI Team,
May I know the pros and cons as I set the PWM_FSET at 3.92kohms and 124kohms with 16bits and 10bits PWM dimming resolution?

I have a question about this design tool. what is the Vminboost mean, is that mean while the voltage is higher( or maybe lower) than Vminboost, we think the LED short happen? Is this voltage detected at LED0-5 pin or Vout…

customer would like to configure LED_SET and PWM_FSET but they doesn't heave suitable resistor value for it so they need series resistor for configuration.
LED_SET: 5.76K(accuracy 1%),customer want: 4.7K(1%)+1K(1%…
Part Number: LP8864-Q1 Could you share the different between LP8864 and LP8866?
I check LP8864 and LP8866 pin compatible completely, so if have some different in actual design?
Look forward to your reply
Part Number: LP8866S-Q1 Hi All
please help me to understand this completely, I just want to make sure.
The maximum dimming ratio for this LED driver is 32000:1, using 152 Hz I want to know if my understanding is correct. (please correct me if i m wrong…
