LTC3588EMSE-1#PBF

LTC3588-1 is a nano power energy harvesting power supply. It integrates a low-loss full-wave bridge rectifier with a high efficiency buck converter to form a complete energy harvesting solution optimized for high output impedance energy sources such as piezoelectric, solar, or magnetic transducers. An ultralow quiescent current undervoltage lockout (UVLO) 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. In regulation, this device enters a sleep state in which both input and output quiescent currents are minimal. The buck converter turns on and off as needed to maintain regulation. It is used in applications such as piezoelectric energy harvesting, electro-mechanical energy harvesting, wireless HVAC sensors, mobile asset tracking, tire pressure sensors, battery replacement for industrial sensors, remote light switches, standalone nano power buck regulator.
