Buck, Buck-Boost, Inverting—No Inductor
Our new family of high voltage charge pumps simplifies the design of DC/DC power supplies by eliminating the need for
an inductor and requiring only a capacitor as the external storage element. These devices provide output currents
up to 250mA and conversion topologies including buck, inverting and buck-boost. Their wide input voltage range
of 2.7V to 48V and 60V transient ride-through and wide operating temperature range (up to 150˚C) make them ideal
for automotive, industrial and medical applications.
