Hi everyone,
I'm wondering if anyone on here can recommend a quality DC-DC converter for me. I'm currently using this one to convert an input ranging from 12-16V (via four lithium batteries) to 24V. My output can actually be anywhere between 18-36V. Output current is in the milliamps range.
The DC-DC converter is being used to give the appropriate power to an array of underwater microphones (hydrophones), so I need the signal to be as clean as possible. The one listed above is pretty good (especially after adding the appropriate filters - namely a 3.3 uF over the output, followed by a low pass RC filter to block anything above 15kHz), but there's still a bit of line noise/harmonics that end up in the acoustic data which isn't present from a bench power supply.
I imagine getting an output from a *battery pack-charge controller-dc/dc converter* network that's as clean as a simple bench power supply is a tall order. But if anyone can recommend anything that comes close, I'd love to know.
