Ratiometric startup
The ratiometric startup is implemented sharing the same soft-start capacitor for a set of the
R6986 device.
Figure 10. Ratiometric startup
As a consequence all the internal current generators charge in parallel the external
capacitor. The capacitor value is dimensioned accordingly with Equation 12:
Equation 12
where nR6986 represents the number of devices connected in parallel.
For better tracking of the different output voltages the synchronization of the set of
regulators is suggested.
