LP5012: Support is needed

Part Number: LP5012

Tool/software:

Hello,

im working on an IOT device that combine an MCU and a LP5012 LED driver.

my purpose is to run an LED driver on a constant current of 20 mA

i have create the following circuit using LP 5012

when trying to communicate with via the i2c, i cannot find the device. 

I want to validate my schematic and design, anyone see any problem ? 

attached is my schematics.



Also im aware that there is no pull up resistors on the schematic.

Im using an MCU which has an internal PU resistors. 

  • Hello Beck,

    Can you please show me how you connect the EN pin since I only noticed that the EN pin is connected to GND by a resistor? And can you please measure the if there is a 1.8V VCAP voltage on VCAP pin?

    BR, Jared
