I just attended a TI Web-seminar in where they talked about their new line
of PTH power modules which include a new feature that they call Turbo Trans.
Turbo Trans allows the user to custom tune the module to meet a specific
transient load requirement. Tuning is accomplished with a single external
resistor. They claim that by using TurboTrans one can achieve a reduction in
bulk output capacitance which leads to an increase in ESR.
Has anyone had any experience using this feature?
The link below has more information.

Thanks, I hadn't seen that software before. It's missing the
ability to optimize what I really care about as a user of the
regulator - the closed loop output impedance. I claim that if
you optimize the closed loop response, one consequence is that
you'll have adequate phase margin. On the other hand, optimizing
the open loop response won't guarantee me the best closed loop
response.
