Boost converter will deliver 15V from 500mV

Linear Tech has introduced a boost converter that starts from 1.8V minimum, but will run with inputs from 0.5-5.5V.

It is synchronous, with 1.5A switches, delivering up to 400mA at 12V from 5V.

“Its 1.5A current limit makes it well suited for input current…
