LP8866S-Q1: SCH Reivew

Hi, Xiaowei

Sure, I will review it and give you a feedback late.

Hi, Xiaowei

Pls kindly let customer to add the device component on the schematic and then we can help to do the review. It is hard to review without correct connect for the external component and the device.

Hi Zhiqian,

LED string parameter as below.

Best Regards,

Hi, Xiaowei

What I mean is pls kindly share the correct connection of the LED pin map schematic again and share with us first.

Hi Zhiqian

Customer feedback currently they have no resource to add this device to their IC library.

Can you please review the updated SCH base on the pin number? Thanks

Hi, Xiaowei

I reviewed the schematic this time, for the next time, pls let customer do the whole lib and schematic first. It is hard to checking with mismatch wire connect for different pin.

• Add a pull down resistor on the PWM pin
• Ensure there are pull up resistor on SCL/SDA
• The cap on OUT pin changes to 1nF
• ISNS/ISNSGND needs a differential layout, add a same resistor on ISNSGND.
