Note 1: Maintain a minimum of 0.4V headroom between input and output voltage to meet performance specifications.
Note 2: Tantalum or similar with additional ceramic as needed to reduce ripple current in external input capacitors. See Figure 26. When using more than
1000µF of output capacitance, input filter inductor should be reduced to <0.3µH or input capacitance should be increased to match output capacitance.
Consult factory for more demanding applications. Also refer to Application Considerations section of this datasheet.
Note 3: The over-current shutdown threshold for a short over-current pulse can be as high as 50A when trimming up a wide trim unit above 1.2V.
Note 4: When trimming a 0.9V unit to less than 0.88V with more than 1000µF of output capacitance, consult factory for trim circuit recommendations. This
also applies to trimming a 1.0V unit below 0.95V.
Note 5: Power derating curves are measured using an evaluation board consisting of 6 layers of 2 ounce copper.
Note 6: Wide trim option unit has a setpoint of 0.753V and a trim range of 0.85V-3.6V.
Note 7: In remote sense applications, when trimming down, the trim-down resistor should be connected to the sense pin for more accurate trimming results.
Note 8: User should allow sufficient transient response headroom between the module’s local output and the minimum OVP threshold.
