Designing for Very Fast Load Transients
SLTS208I – MAY 2003 – REVISED MARCH 2009 ............................................................................................................................................................. www.ti.com
The transient response of the DC/DC converter has been characterized using a load transient with a di/dt of
1A/s. 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 can only be 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 the data sheet, or the total amount of load
capacitance is above 3000
F, the selection of output capacitors becomes more important.
