Linear Technology LTC3330

LTC3330; wave bridge rectifier and a high voltage buck converter, harvests energy from p iezoelectric, solar, or magnetic source s. The primary cell input powers a buck -boost converter capable of operation d own to 1.8V at its input. Either DC/DC converter can deliver energy to a singl e output. The buck operates when harves ted energy is available, reducing the q uiescent current d.

The LTC®3330 integrates a high voltage energy harvesting
power supply plus a DC/DC converter powered by a primary
cell battery to create a single output supply for alternative
energy applications. The energy harvesting power sup-
ply, consisting of an integrated full-wave bridge rectifier
and a high voltage buck converter, harvests energy from
piezoelectric, solar, or magnetic sources. The primary cell
input powers a buck-boost converter capable of opera-
tion down to 1.8V at its input. Either DC/DC converter
can deliver energy to a single output. The buck operates
when harvested energy is available, reducing the quiescent
current draw on the battery to essentially zero, thereby
extending the life of the battery. The buck-boost powers
VOUT only when harvested energy goes away.
A low noise LDO post regulator and a supercapacitor
balancer are also integrated, accommodating a wide range
of output storage configurations. Voltage and current set-
tings for both inputs and outputs are programmable via
pin-strapped logic inputs. The LTC3330 is available in a
5mm × 5mm QFN-32 package.
