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…
Part Number: LP8556 Hello,
The LP8556 datasheet has a table of recommended inductors, however the input voltages listed do not include a 5V input. Should I use the 2.7-4.4V recommendations or the 5.4V-8.8V recommendation?
Thanks,
Michael
Part Number: LP8556 Hello,
I am looking at the LP8556 because I like its capability of pure current control mode. In order to use this pure current control it looks like I can only do this when using a combination of I2C and PWM.
I am finding the setup…
Part Number: LP8556 Hi team,
In the datasheet it says the current limit minimum and maximum value are for DSBGA package. I wonder the minimum and maximum value for QFN package.
Best Regards,

Part Number: LP8556 Hi Team,
Our customer are doing exception tests. After short-circuiting the VOUT of the LP8556 to the ground, there will be smoke and the chip will be damaged. We checked the SPEC of LP8556 and found that this chip supports the OCP…

Dear Team,
We had another project reuse the LP8556SQ and face system crash issue once the host control BL via PWM.
Could you help to review schematic especially the RFset R150 / RIset R156 and L4?
BL LEDs are 2 lane 16~20.4V/20mA. System…
