Description

The LTC3588-1 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 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.Output Voltage (Switcher)UVLOQuiescent CurrentLTC3588-1Selectable 1.8V, 2.5V, 3.3V or 3.6V4.04V(Rising)2.87V(Falling)950nA (No Load)450nA (UVLO)LTC3588-2Selectable 3.45V, 4.1V, 4.5V or 5V16V(Rising)14V(Falling)1,500nA (No Load)830nA (UVLO)ApplicationsPiezoelectric Energy HarvestingElectro-Mechanical Energy HarvestingWireless HVAC SensorsMobile Asset TrackingTire Pressure SensorsBattery Replacement for Industrial SensorsRemote Light SwitchesStandalone Nanopower Buck Regulator
