Analog Devices, Inc. announced a power management unit (PMU) designed to enable faster and more efficient energy harvesting in IoT applications where energy is scarce. Due to its unique circuit design, the ADP509x is among the most efficient energy harvesting PMUs on the market, converting harvested power down to the 16 μW to 100mW range with only sub-μW operation losses. The ADP509x also delivers the fastest cold-startup time available today. Devices relying on energy harvesting in low energy conditions often have to slowly accumulate enough energy to turn on, resulting in long delays before the device can start sensing, processing, and transmitting. This can result in missed data collection, slow operation, and poor user experience. The ADP509x PMU solves these problems with an innovative multiple-power-path design, which enables faster startups and smoother operation.
