Booster Modules from ALD Help to Enhace DC or AC voltage

Advanced Linear Devices has released the next product in the new family of MicroPower Step-up Low-Voltage Booster Modules. As a self-powered, self-starting module, the EH4205 is a new addition to the next series of ALD’s low-voltage booster modules, which can convert very low power or voltage to higher DC or AC voltage. Because of an exclusive design parameter, it can hibernate in a zero-power state, until the input of the connected energy source becomes active. The device is no outside power source or battery in need. The product starts up, accumulates energy, and functions as long as the source is active. The result is an always on, always ready, always charged energy source. This extremely low-level captured energy is manipulated within the booster module and outputted, as higher DC or AC voltages capable of powering today’s energy harvesting (EH) modules. The EH4205 is matched to power ALD’s 300 series EH modules, but can power any EH module.

The next generation module is unique in its ability to manage an ultra-low energy sources that were formerly too low to capture, typically 75 mV.

The portfolio has been the lowest energy capture thresholds in the industry. Beginning with the EH4205 ultra-low voltage booster module, this series has a lower minimum startup of the earlier module with an input voltage of 75 mV vs. 120 mV. The minimum operating input power has been reduced to 230 uW from 250 uW. The significant change in milliwatts brings some formerly elusive energy sources, such as electro-magnetic coils and thermoelectric energy generators, into the viable Energy Harvesting source category. This makes the EH4205 the only device on the market that can harvest energy from sources beyond the typical competitive landscape, by almost 400%.
