Description

LTC1144IS8#PBF - Linear Technology

The LTC1144IS8#PBF is a high-efficiency, monolithic charge pump voltage converter manufactured by Linear Technology. This component is designed to provide a versatile solution for applications requiring voltage inversion or doubling with a minimal number of external components. It is particularly suited for battery-powered systems where extended battery life is essential and for space-constrained applications due to its small footprint.

Featuring a wide input voltage range of 1.5V to 10V, the LTC1144IS8#PBF can deliver an output current of up to 10mA with a voltage inversion efficiency of over 99% at 100μA. This high efficiency is maintained across a broad range of input voltages and load currents, making it an excellent choice for a diverse set of applications.

The device operates in two modes: voltage inverter and voltage doubler. In inverter mode, it inverts the input voltage with a very low voltage drop, while in doubler mode, it provides an output voltage that is approximately twice the input voltage. The LTC1144IS8#PBF also features a low quiescent current, which is particularly beneficial for battery-powered devices, as it helps to minimize power consumption when the device is in standby mode.

Another notable feature of this charge pump is its ability to operate at high frequencies, up to 10kHz, which allows for the use of smaller external capacitors. This results in a more compact overall design. The LTC1144IS8#PBF is packaged in an 8-lead SOIC, which provides a balance between space-saving and ease of handling during manufacturing processes.

In summary, the LTC1144IS8#PBF from Linear Technology is a versatile, high-efficiency charge pump voltage converter that is ideal for a wide range of applications, including but not limited to portable electronics, backup power supplies, and negative voltage generation for operational amplifiers and analog signal processing circuits.
