Component values inside the LM5022 current mode controller?

In the LM5022 datasheet block diagram (page 8) there is a 1.4V voltage source, and a divider comprising a 100kohm resistor and a 50kohm resistor. (these are inbetween the error amplifier and the pwm comparator).
Do you know what is the part to part tolerance on these values?

The loose tolerance on the above mentioned internal components means that the LM5022 will not be good for use in three 2500W boost converters which we need to be in parallel (Vin=200VDC, vout=400VDC). They will be in parallel with a single external error amplifier feeding back to all three LM5022’s.

I am thinking the HV9910B will be better for this..

Though preferably it would be a controller which allows the internal reference on the current sense comparator to be set with a more accurate external reference..this would give more accurate current sharing between the three paralleled Boost converters.
And we'd also like them to be sync'able. Anyone know of such a chip?
 

MCP1630V is one but could anyone give names of others?
