Linear Technology Corp.’s LTC3588-1 is a complete energy harvesting solution optimized for low energy sources, including piezoelectric transducers. The device integrates a low-loss, full-wave bridge rectifier with a high efficiency buck converter to harvest ambient vibrational energy via piezoelectric transducers, and then convert it to a well-regulated output to power application microcontrollers, sensors, data converters and wireless transmission components.
The LTC3588-1 operates from an input voltage range of 2.7V to 20V, making it ideal for a wide array of piezoelectric transducers, as well other high output impedance energy sources. Its high efficiency buck DC/DC converter delivers up to 100mA of continuous output current or even higher pulsed loads. Its output can be programmed to one of four fixed voltages—1.8V, 2.5V, 3.3V or 3.6V—to power a wireless transmitter or sensor.
