TPS652353: Disable Power output via I2C

Hi,

I am using TPS652353 in my design and using I2C to control it.

It works fine for setting voltage levels, I am using 13.4V and 18.2V which work fine.

But. when I try to disable the output by writing 0x00 in Control 2 register, the voltage output comes to 14.6V instead of 0V.

What can be the issue?

This is what I am writing via I2C to switch off the LNB output

    Wire.beginTransmission(0x09);   //address of the device
    Wire.write(0x01);               //control2 register address
    Wire.write(0x00);               //data byte
    Wire.endTransmission();
