Other Parts Discussed in Thread: LM5118, LM5156, LM5155
Hi, we have a varying voltage source (from a generator) that can have a wide voltage range from 6-30V. This voltage has to be regulated to a stable 24V output for an external controlboard that use 10-12W of power.
Can we use the LM2577 in a forward converter mode to achieve this? I only see that the LM2577 is a boost converter, so if the voltage input is > 24V then it needs to operate as a buck converter... will it automatically handle this?
If this is not possible can it then be achieved with a flyback converter? If yes which transformer can I use? In the datasheet the proposed transformers are in the range 4-6V and 18-36V, so not really feasable for my application - but maybe the 18-36V can also go lower?
Lastly is it true that the built-in current limiter ofLM2577 is not working in forward converter mode (based on note 3 on page 4 of the datasheet).
FYI: I have been looking at LM5118, but it is much more complicated than the LM2577.
