The LTC1046IS8#TRPBF is a low noise, synchronous N-Channel MOSFET Switching Regulator from Linear Technology Corporation. The regulator features a fixed-frequency, current-mode control architecture, which provides superior control loop performance. The device is designed for low-noise applications and operates without the need for an external capacitor or transformer. It offers a wide output range that can be adjusted from 0.5V to 7V and an adjustable output current up to 2.5A. It is specifically designed for low-noise applications such as audio amplifiers and high sampling rate ADC/DAC interfaces.
The LTC1046IS8#TRPBF is ideally suited for use in applications such as power management, DC to DC conversion, motor control and current-mode control in power conversion. It can be used as a low-noise switching regulator, DC to DC converter, or motor control in a wide range of applications. It is also suitable for use in noise sensitive applications such as audio amplifiers, RF amplifiers and digital signal processing systems.
The working principle of the LTC1046IS8#TRPBF is based on a current-mode control architecture. The regulator has an on-chip oscillator, enabling it to be used as a stand-alone device without the need for an external clock source. The oscillator generates a fixed frequency, allowing for precise regulation of the output voltage. The device features a current-mode, peak current limiter, allowing the regulator to remain stable at any load, and providing quick and precise switchover from light to heavy load conditions.
The current-mode control architecture allows for precise loop stabilization and fast line transient response, making the LTC1046IS8#TRPBF suitable for high frequency and noise sensitive applications. The device also features a 4-pin current sensing input, which enables the regulator to be used as an adjustable current source. The regulator also offers a temperature shutdown feature to protect the device in the event of an over-temperature condition.
In summary, the LTC1046IS8#TRPBF is a low noise, synchronous N-Channel MOSFET Switching Regulator from Linear Technology Corporation. It features a current-mode control architecture, providing superior loop performance and fast line transient response. It is designed for low-noise applications such as audio and high sampling rate ADC/DAC interfaces, and is ideally suited for use in applications such as power management, DC to DC conversion, motor control and current-mode control in power conversion.
