LP5024: LED not turning ON but I2C slave read/write is successful.

Part Number: LP5024

Hi

I have rig up LP5024 circuit with two LEDs (Green to OUT0 and RED to OUT1). I reffered the reference design from TI.

Device VCC is 3.3V. I am using external I2C master controller (AADVARK tool) to do basic read/write operation. I am successfully able to read all register reset values and also change the register value as per the datasheet.

I just write DEVICE_CONFIG0 register to 40h to enable the chip. But i donot see the LEDs turned ON.

I checked the anode = 3.3V, Cathode= 1.7V (Green) and 2.7V (red).  Iam not sure what is missing. I should be easily control led . Let me know if anything missing.

Thanks
