Correct me but I don't think such a thing exists as a chip.
I want to use a 9v battery to get a variable 9-14V regulated output, but sticking a regulator on the end of a chip step-up convertor doesn't seem too efficient.
Anyone know of a chip that will do the whole job that requires just connecting up a pot to control the output voltage? I don't need much current, say 20mA. Thanks
