LTC3588 集成了一個(gè)低損失全波橋式整流器和一個(gè)高效率降壓型轉(zhuǎn)換器，以造就一款專為高輸出阻抗能源 (例如：壓電換能器) 而優(yōu)化的完整能量收集解決方案。一種具有一個(gè)寬遲滯窗口的超低靜態(tài)電流欠壓閉鎖 (UVLO) 模式允許電荷在一個(gè)輸入電容器上積聚，直到降壓型轉(zhuǎn)換器能夠有效地將一部分存儲(chǔ)電荷轉(zhuǎn)移至輸出為止。當(dāng)處于調(diào)節(jié)模式時(shí)，LTC3588-1 將進(jìn)入一種睡眠狀態(tài) (在該狀態(tài)中，輸入和輸出靜態(tài)電流都非常小)。降壓型轉(zhuǎn)換器根據(jù)需要接通和關(guān)斷，以保持調(diào)節(jié)作用。

　　The LTC?3588-1 integrates a low-loss full-wave bridge rectifi er with a high effi ciency 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 （UVLO） mode with a wide hysteresis window allows charge to accumulate on an input capacitor until the buck converter can effi ciently transfer a portion of the stored charge to the output. In regulation， the LTC3588-1 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. Four output voltages， 1.8V， 2.5V， 3.3V and 3.6V， are pin selectable with up to 100mA of continuous output current; however， the output capacitor may be sized to service a higher output current burst. An input protective shunt set at 20V enables greater energy storage for a given amount of input capacitance.
