ADIDC2042A
Overview
The DC2042A is a multi-source energy harvesting evaluation board featuring the LTC3588-1, designed to demonstrate the conversion of ambient energy into regulated power. It supports harvesting from various sources including piezoelectric, solar, and thermal gradients with an ultra-low quiescent current. The board provides a complete solution for managing harvested energy, including a bridge rectifier and a high-efficiency buck converter.
Why Choose This Part
It features an ultra-low quiescent current of 450nA and includes an integrated low-loss full-wave bridge rectifier to maximize energy recovery. The LTC3588-1 provides selectable output voltages (1.8V, 2.5V, 3.3V, 3.6V) and includes a PGOOD signal for power sequencing. The board is designed to operate with input voltages up to 18V, making it compatible with a wide range of transducers.
Applications
Key Specifications
Getting Started
To begin evaluation, connect a high-impedance source such as a piezoelectric transducer to the input pins or a solar cell to the dedicated terminals. Configure the output voltage using the onboard jumpers to set the D0 and D1 logic pins of the LTC3588-1. Monitor the VOUT and PGOOD pins to observe the regulation and power-up timing relative to the energy storage capacitor's state of charge.
