Simple way to boost voltage ?
Hi, I need a low part count and low cost way to boost a low voltage supply. I currently have a large buck powering the device core power between .65-.8v. I need a way to take this core voltage and boost it to .8-.9v @ ~ 1 A. Most boost converters dont work in these voltage ranges, and was hopeing there is another type of solution since the voltages are so close together.
I also have the option of taking a multiple of core voltage and converting it down to .9v with a buck (this is a series of devices, each ground plane is separated potential difference of the core power, so I "could" ground a buck supply two devices down the series (ie if core voltage is set to .7v, the buck would be fed 1.4v -> .9v), but this would get expensive as I would need a buck converter for each device in the series.
