LTC3330EUH#PBF

The LTC3330EUH#PBF by LT is a specialized power management integrated circuit designed for energy harvesting and battery life extension. This nanopower buck-boost DC/DC converter features dual input sources: an energy harvesting input ranging from 3.0V to 19V and a primary cell input from 1.8V to 5.5V.

Key electrical specifications include an ultralow quiescent current of 750nA at no-load, enabling efficient operation in low-power scenarios. It can deliver up to 50mA of output current. The device integrates a low-loss full-wave bridge rectifier and an input protective shunt capable of handling up to 25mA at voltages greater than or equal to 20V.

This IC is housed in a compact 5mm x 5mm QFN-32 package, making it suitable for space-constrained designs. It is designed to power applications such as wireless sensor networks, particularly in remote industrial environments where traditional power connections are unavailable. The dual-input design allows for seamless power management between harvested energy and a primary battery source.

Applications include powering dust motes from piezoelectric transducers and extending the operational life of battery-powered devices. The LTC3330EUH#PBF supports programmable DC/DC and LDO output voltages, as well as programmable buck UVLO and buck-boost peak input current, offering flexibility in power system design.
