APPLICATION NOTE 411
Derive 12V From 8V to 15V Input

Abstract: The buck/boost converter successfully addresses the challenge of regulating a 12V from the wide
input-voltage swing associated with the sealed lead-acid battery.


Derive 12V From 8V to 15V Input

You can't derive a regulated 12V output from a 12V lead-acid battery by using a simple boost converter because
it it can't accept an input voltage that is greater than its output voltage. Conversly, a buck converter is a
combination of buck and boost circuitry that successfully addresses the challenge of the wide input-voltage swing
associated wit……
