Packages The LTC®3588-1 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 …
