Kit Overview

 

Demonstration Circuit 1459B (DC1459BDC1459B) is an energy harvesting power supply featuring the LTC3588-1LTC3588-1/LTC3588-2LTC3588-2. The LTC3588 integrates a low-loss full-wave bridge with a high efficiency buck converter to form a complete energy harvesting solution optimized for high output impedance energy sources such as piezoelectric transducers.

 

An ultralow quiescent current undervoltage lockout mode with a wide hysteresis window allows charge to accumulate on an input capacitor until the buck converter can efficiently transfer a portion of the stored charge to the output. Four output voltages are pin selectable with up to 100mA of continuous output current. A power good comparator produces a logic high referenced to VOUT on the PGOOD pin when the converter reaches the programmed VOUT, signaling that the output is in regulation. The LTC3588EMSE-1LTC3588EMSE-1/LTC3588EMSE-2LTC3588EMSE-2 are available in a 10-lead (3mm x 3mm) MSE surface mount package with exposed pad.
