Designing for Very Fast Load Transients
The transient response of the dc/dc converter is characterized using a load transient with a di/dt of 1 A/μs. The
typical voltage deviation for this load transient is given in the data sheet specification table using the optional
value of output capacitance. As the di/dt of a transient is increased, the response of a converter's regulation
circuit ultimately depends on its output capacitor decoupling network. This is an inherent limitation with any dc/dc
converter once the speed of the transient exceeds its bandwidth capability. If the target application specifies a
higher di/dt or lower voltage deviation, the requirement is met with additional output capacitor decoupling. In
these cases, special attention must be paid to the type, value, and ESR of the capacitors selected.
If the transient performance requirements exceed that specified in this data sheet, or the total amount of load
capacitance is above 3,000 μF, the selection of output capacitors becomes more important.

Capacitor Supplier Verification
Please verify availability of capacitors identified in this table. Capacitor suppliers may recommend alternative part numbers because of
limited availability or obsolete products. In some instances, the capacitor product life cycle may be in decline and have short-term
consideration for obsolescence.
RoHS, Lead-free and Material Details
Please consult capacitor suppliers regarding material composition, RoHS status, lead-free status, and manufacturing process
requirements. Component designators or part number deviations can occur when material composition or soldering requirements are
updated.
N/R – Not recommended. The capacitor voltage rating does not meet the minimum operating limits.
The voltage rating of this capacitor only allows it to be used for output voltages that are equal to or less than 5.1 V.
