... The output HIGH OUT_LCL from the HIGH SET Input Capacitors LTM4601AHV module should be connected to a low AC impedance DC source. Input capacitors are required to be placed adjacent to the module. In Figure 18, the 10μF ceramic input capacitors are selected for their ability to 19.1 13.3 8.25 handle the large RMS current into the converter. An input bulk capacitor of 100μ ...

... D Output Capacitors The LTM4601AHV is designed for low output voltage ripple. The bulk output capacitors defi ned as C with low enough effective series resistance (ESR) to meet the output voltage ripple and transient requirements. C can be a low ESR tantalum capacitor, a low ESR polymer capacitor or a ceramic capacitor. The typical capacitance is 200μ ...

... Multiphase operation with multiple LTM4601AHV devices in parallel will lower the effective output ripple current due to the interleaving operation of the regulators. For example, each LTM4601AHV’s inductor current of a 12V to 2.5V multiphase design can be read from the Inductor Ripple Current versus Duty Cycle graph (Figure 3). The large ...

... Excel tool (Refer to the Linear Technology μModule Power Design Tool). Fault Conditions: Current Limit and Overcurrent Foldback LTM4601AHV has a current mode controller, which inher- ently limits the cycle-by-cycle inductor current not only in steady-state operation, but also in transient. To further limit current in the event of an overload condition, the LTM4601AHV provides foldback current limiting ...
