Bias power requirement of TNY287 Flyback SMPS controller

[ocset]

Hi,
We are  using the TNY287 for a  offline isolated Flyback SMPS (10W), and we are powering the TNY287 from a bias winding. (schem attached)

Page 6 of the  datasheet says we must supply 1mA   to the TNY287,  however page 12 says that  the TNY287 requires 550uA.

Page 15 of the datasheet states that if TNY287 us supplied with over 4mA , then it will shut down.
Please advise if the TNY287 requires 550uA  or 1mA?
We need to know, because  when our secondary is light loaded, our bias coil collapses from 24V down to 14V.........we want to set the feed resistor  (R18) to as low value as possible (feed resistor is the resistor that feeds the BP/M pin from  the bias coil)  so as to reduce dropout of the bias coil in light load as much as possible.

If the 550uA figure applies, then we can set the feed resistor to  11k, but if the 1mA  figure applies, then we must set the feed resistor to 6k2.
If we set the feed resistor to 6k2, then when the secondary is loaded, and the bias coil  thence goes up to 24V,  then we are feeding the  TNY287 perilously close to the 4mA  maximum.
Please advise the actual bias current draw of the TNY287.

Just read the fine datasheet:

They state: If you supply enough current (1mA recommended) into that pin, you reduce the devices power dissipation by disabling the HV regulator. The same pin is used for e.g. OVP to shut down the chip in case of feedback loop failure at some higher current threshold (4mA). So one might think, if you supply less current, it either may simply take away part of the power dissipation, or cause some wrecking and havoc - whatever, I can't answer this.
So it's up to your engineering skills to find a suitable resistor or add more more components to achieve your goals.
