LTC3588 Energy Harvesting Power Supply Module Board for Arduino

The LTC3588 is an energy harvesting module designed to power ultra-low-consumption systems from alternative sources such as piezoelectric elements or micro-generators.

This board integrates a low-loss full-wave bridge rectifier, a high-efficiency hysteretic buck DC/DC converter, and undervoltage lockout (UVLO) management. It is ideal for autonomous IoT applications and wireless sensors.

Specifications

• Input quiescent current: 950 nA (regulated output, no load)
• Quiescent current in UVLO: 450 nA
