3.0 - 3.6Vin 15A
ELECTRICAL CHARACTERISTICS (continued) - NQ03xxxVMA15 Series
NOTES
Note 1: Maintain a minimum of 0.35V headroom between input and output voltage to meet performance specifications.
Note 2: Wide trim option unit will perform as the model with the output voltage that it is trimmed to. Applies to all specifcations where values differ by Vout.
Note 3: Tantalum or similar with additional ceramic as needed to reduce ripple current in external capacitors. See Figure 21. Output capacitance of
<1000µF. Additional input capacitance equal to half of the output capacitance is recommended when more than 1000µF of output capacitance is used.
Consult factory for more demanding applications. Also refer to Application Considerations section of this datasheet.
Note 4: 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 5: Larger input capacitance of at least half of the output capacitance is recommended when using >1000µF on a 2.5V output.
Note 6: When trimming the output voltage to less than 0.88V with more than 1000µF of output capacitance, consult factory for trim circuit recommendations.
Note 7: Power derating curves are measured using an evaluation board consisting of 6 layers of 2 ounce copper.
Note 8: Wide trim option unit has a setpoint of 0.9V and a trim range of 0.85V-2.75V.
Note 9: In remote sense applications, when trimming down, the trim-down resistor should be connected to the sense pin for more accurate trimming results.
Note 10: Indicates worst case specification for 0.9V unit. Higher output voltage units have a tighter specification range. The wide-trim unit carries the OVP
set point of a 2.5Vout unit, which has a worst-case maximum OVP trip level of 135%.
