*Bulk capacitance is optional if V
for those who wish to perform additional stability analysis.
Multiphase operation will reduce effective output ripple as
a function of the number of phases. Application Note 77
discusses this noise reduction versus output ripple cur-
rent cancellation, but the output capacitance will be more
a function of stability and transient response. LTpowerCAD
also calculates the output ripple reduction as the number
of phases increases.

Burst Mode Operation
The LTM4616 is capable of Burst Mode operation on each
regulator in which the power MOSFETs operate intermit-
tently based on load demand, thus saving quiescent current.
For applications where maximizing the efficiency at very
light loads is a high priority, Burst Mode operation should
be applied. To enable Burst Mode operation, simply tie the
MODE pin to V
the inductor is set to approximately 20% of the maximum
