The LTC3588-1 from Linear Technology Corp., Milpitas, CA, 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 device is designed to interface directly with a piezoelectric or alternative AC power source, rectify a voltage waveform, and store harvested energy in an external storage capacitor while dissipating any excess power via an internal shunt regulator. Features include a 2.7–20 V input operating range; selectable 1.8 V, 2.5 V, 3.3 V, or 3.6 V output voltages; and 950 nA input quiescent current (output in regulation, no load).
