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…
Part Number: LP8556 Hi Team,
Could you possible help to check if LP8556SQE-09 could support I2C configuration? From datasheet it shows PWM only support. But from EVM design, it seems this device could support I2C configuration, could you possible help…

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…
Part Number: LP8556 Hi team,
My customer wants to design in LP8556, but their LED need 100mA.
Can just short the LED pin(pin LED1 and pin LED2) for this 100mA LED light?

Hi,
Seeking LED driver with following requirements:
1. I2C control
2. Analog brightness control (that needs to be completly turn off at one end)
3. LED will be 2S2P…
