Power Management Boards
In most instances, it is desirable to convert the output of the AC Power Cell to DC power. To
enable the user to do this quickly, the Evaluation Kit includes two Power Management Boards
which rectify the AC Power Cell output to DC power regulated to a constant voltage. It is
important to note that the harvesting power can be optimized by selecting the proper Power
Management Board for the application. For applications where the AC Power Cell creates a high
AC voltage (up to 20V), the LTC3330 Power Management board should be used. For applications
where in the AC Power Cell creates low AC voltages (less than 6V), the Torex Power Management
board should be used. For impulse mode of operation, selection of the best power management
board should be determined on an application by application basis. Please contact microGen
Systems for further discussions on your specific application.
LTC3330 Power Management Board
Product Description
The LTC3330 Power Management Board uses a low leakage single phase diode bridge to rectify
an AC voltage. A Linear Technologies LTC3330 nanopower DC/DC converter is laid out in a buck
configuration with a 22uH inductor. The switching converter allows for wide range on input
Voltages and a configurable output between 1.8 and 5 Volts. The board is designed to convert
the output power signal of the AC Power Cell to a useable DC power signal. The board connects
directly to the AC Power Cell via two 3-pin receptacles located at either end of the board.
