LT customer service is second to none, ADI not interested in kids (me) or the little guy. LT got a project of mine off the ground (literally), and ended up with alot of news coverage for it (BBC click program was one).
what is your problem? if it is quick I can answer it. if not, I can put you in touch with someone who can
Whats a manualLT is a bit rigid. When something doesn't fit into the framework (e.g. Website), they make it fit the existing framework. Related parts and development kits is a prime example. It's much easier to find related ("used together during development") stuff on AD's website.
I liked National Semiconductor's datasheets more than TI's. TI's TTL databook was great though. TI lost that ability.
OK, you have two parts that are similar and it's difficult on LT's website to choose one over the other.
Back in the 80's when AD had another life, I was contemplating purchasing a data acquisition system, the uMac-4000 and I asked for a manual before purchasing. No one had ever asked for one before. This was a $5000.00 USD product back then.
For the ESD I suspect 2kV Human Body Model. Most of our devices conform to that unless it connects to the outside world - like with an RS232 chip in which case it will be higher .
Regarding the loop response, this depends on the transformer and the output cap and its ESR, so this is why we would not specify it - it is determined too much by the external components that we have no control over. Indeed I don't think we specify the loop characteristics of any of our dc/dc converters for this reason. If you really need to work out the loop response, you need to apply a step load to the output and see how it rings. If it rings excessively, increase the output capacitance (since you cannot compensate the output of the error amplifier). If you really want optimum loop response, the LT3748 is a flyback that gives you access to the output of the error amplifier so you can tailor the loop response to your needs. In this case, you will need a Bode Analyser to inject a signal in to the loop to measure the gain and phase margin. I recommend the Omicron Bode 100 from personal experience.
You could try LTspice, but the LTspice models are designed for transient analysis (time on the x axis) not frequency analysis (freq on the x axis) so the models probably will not give you a true representation of the loop characteristics
Whats a manual
