Note 1: L = 2.2uH, DCR 80 mΩ, COUT_effective = 10uF. If the user desires different VOUT configurations from the default CMI, contact
active-semi. Default CMI is what sets the output voltages of the regulators on POR event. Parts can be ordered with different CMI
settings, to fit the specific customer output voltages in the application.
Note 2: Depends on ordering options (vout, ilim, etc), and external inductor selection.
Note 3: Device needs to be tuned for these frequencies. Contact active-semi for a different default operating frequencies or voltage.
