Increased operating time of space-constrained, ultra-small devices
Increasing solar charging efficiency with MPPT method


Designers of wearable and IoT devices must simultaneously meet the dual requirements of ultra-small size and long operating time. Maxim Integrated Korea today announced the launch of the MAX20361 single- and multi-cell solar charger with Maximum Power Point Tracking (MMPT).

The MAX20361 charger extends runtime by bringing solar charging capabilities to space-constrained devices. It features adaptive MPPT to improve overall system efficiency and a separate charge gauge that displays efficiency in real time.

“This new product represents a new auxiliary power source possibility for continuously charging the device’s battery,” said Frank Dowling, managing director of Maxim’s Industrial and Healthcare business unit. “For example, a 300mA/hour battery system that runs for three weeks could be extended by more than 50 percent by charging it daily with about 30mW of solar power.”
