The LTC1842IS8#PBF is an Integrated Circuit (IC) component manufactured by Linear Technology Corporation (now part of Analog Devices Inc.). This IC belongs to the LTC184x family of ultralow power boosting charge pump voltage inverters. It is widely used in various applications where voltage inversion or double voltage conversion is required.
The LTC1842IS8#PBF is available in an 8-pin SOIC (Small Outline Integrated Circuit) package. It operates over a wide input voltage range of 1.8V to 5.5V, making it suitable for use with a broad range of power sources. The output voltage of the IC can be set to either -VIN (negative input voltage) or -2VIN. It is capable of sourcing up to 60mA of output current, allowing it to power multiple loads simultaneously.
One of the key features of the LTC1842IS8#PBF is its high efficiency. It utilizes a charge pump conversion technique that ensures minimal power loss during the voltage inversion process. This efficiency is particularly beneficial in battery-powered systems, where power conservation is crucial.
The IC incorporates an internal Schottky diode, eliminating the need for any external components for voltage inversion. This simplifies the design and reduces the overall cost of the system
