... Multiphase operation with multiple LTM4603HV devices in parallel will lower the effective output ripple current due to the interleaving operation of the regulators. For example, each LTM4603HV’s inductor current of a 12V to 2.5V multiphase design can be read from the “Inductor Ripple vs Duty Cycle” (Figure 3). The large ripple current ...
