MC34709 linear regulators are sequentially enabled in time slots of 1.6 ms steps, not 2.0ms according to the Datasheet

Hi all,

I have done experiments in the  MC34709, and after testing the timing sequence I have seen that the enabling sequence of the regulators is happening every 1.6ms instead of 2ms as it is on the datasheet. Why is this happening? why it is not every 2ms? The regulators have loads and I am able to see 2 of them at a time in the OSC. Please check the images attaches, specially 0b & 1b.

 

Regards,

Luis Guevara
