Matrix Mercury DC/DC Boost Converters are ideal for deployment in circuits where the harvesting and management of surplus energy from low input voltage sources is required.

The Matrix DC/DC converter is the world's smallest energy harvesting boost converter with the highest conversion efficiency according to Matrix Industries. 

The device has nanopower energy harvesting synchronous boost with microwatt cold-start, input impedance matching, and regulated output. It is available in a 10-lead, 3mm x 3mm DFN package and a 9-bump 12mm x 10mm WLP package. 


Matrix Mercury DC/DC Boost Converter

Matrix Mercury DC/DC Boost Converter features patented transformer reuse topology that operates as a flyback converter and can run on input power as little as a few microwatts. An impedance matching feature prevents a constant impedance load and allows high-efficiency energy harvesting across a full range of input voltages.

Multiple input voltage options are available based on the transformer and the 8-bit-on-chip ADC is able to detect when voltage over current exceeds the pre-programmed limit. When this occurs, the input is switched off to ensure reliable operation. The measurement's result is then transmitted via a two-wire interface to a microcontroller. 

Matrix Industries has stated that the Mercury DC-DC converter is poised to lead a new era of energy harvesting, a new high of efficiency for maximizing power transfer, and minimized power leakage with active input monitoring. These promises are delivered by the likes of VIN as low as 10mV (VOC=20mV, RIN =5Ω) to VOUT of up to 5V, up to 80% peak conversion efficiency, and Built-in VOC monitoring through an 8-bit ADC respectively. 

The operating temperature of the DC/DC converter is -40°C to +85°C.


Potential Applications

The Mercury DC-DC converter has several use cases. 

Potential applications include remote sensors deployed in industrial sites, processes, and machinery, thermal energy harvesting, portable medical devices—including 'smart' and IoT-ready devices—consumer wearables such as smartwatches, smart meters, predictive maintenance, and building automation.
