Compact and High Efficiency Solar Harvesting Solution to Increase Runtime of Space-Constrained Wearable and IoT Applications
Designers of space-constrained designs can now significantly increase runtime with the MAX20361 single-/multi-cell solar harvester with maximum power point tracking (MPPT) from Maxim Integrated Products. This new MAX20361 solar harvesting solution does not compromise between size and runtime for a wearable or IoT device. By enabling solar charging in these highly space-constrained products, the MAX20361 can extend the runtime of those devices by providing a supplemental power source. This solar harvester reduces solution size by at least half and also increases harvested energy with up to 5 percent better boost efficiency, coupled with an adaptive MPPT approach which can improve the overall system-level efficiency even further.
- Smallest Size: Industry’s smallest solar harvesting solution due to reduced component size and smaller, fewer external components; at least 50 percent smaller solution size compared to the closest competitor.
- Higher Efficiency: Increased boost efficiency maximizes harvested energy with up to 5 percent better boost efficiency than the closest competitor; additional harvesting gains can be achieved through adaptive MPPT features coupled with the unique integrated harvesting gauge for real-time indications of efficiency to optimize performance.
The MAX20361 is available at Maxim Integrated’s website for $2.64 (1000-up, FOB USA); also available from authorized distributors. The MAX20361EVKIT# evaluation kit is available for $57
