LT1084CP-5#PBF Application Field and Working Principle
The LT1084CP-5#PBF is a Linear Voltage Regulator from Analog Devices in the Power Management Integrated Circuit (PMIC) category. It is designed specifically for powering LED lighting arrangements requiring output current of up to 1A. The device has a wide voltage operating range of 6V up to 24V, and is capable of output voltage of up to 24V. The device has a synchronous current mode topology, allowing for efficient operation and control. It features over protection and current limit protection, making it suitable for use in applications requiring protection feature.
Overview of the Features
The LT1084CP-5#PBF features voltage regulation, allowing it to maintain a constant regulated output voltage as the input voltage changes. This enables LED lighting to be powered with a range of common voltage sources such as AC mains, DC solar and vehicle battery systems. The device is capable of providing an output current up to 1A, making it suitable for driving small to medium LED lighting systems. It can also be configured to provide a constant current output, which is more commonly used in LED lighting applications where constant output current is required. In addition, the LT1084CP-5#PBF is equipped with over protection and current limit protection, providing an additional level of safety and reliability for high powered lighting applications.
Applications
The LT1084CP-5#PBF is suitable for use in a variety of high powered lighting applications. It is especially suitable for applications such as street lighting and stage lighting, where the operating voltage may range from 6V to 24V, and where constant output voltage and/or current are required. The device is also suitable for powering LED lighting applications in automotive, industrial and commercial lighting, where it can be used in place of conventional linear voltage regulators. In addition, the device can be used for a variety of other low to medium power applications such as the powering of small circuits, meters, and remote sensors.
Working Principle
The operation of the LT1084CP-5#PBF Linear Voltage Regulator is based around a feedback loop.The circuit contains an operational amplifier and a comparator, which form the feedback loop, and a driver and a pass transistor, which control the output voltage. The input voltage is fed into the integrated circuit and the feedback loop continuously compares the output voltage to the reference voltage. If the output voltage is lower than the reference voltage then the output voltage is increased and if it is higher than the reference voltage then the output voltage is decreased.
The pass transistor is used to control the output voltage of the regulator and can be configured by the selection of an external resistor. The resistance of the transistor is proportional to the input voltage. The higher the voltage, the lower the resistance and the higher the current. The output voltage is then regulated by the combined action of the pass transistor and the feedback loop.
The output current is controlled by the driver and the pass transistor, which are both controlled by the feedback loop. The driver controls the pass transistor by applying a current, which is proportional to the input voltage. This current is then used by the feedback loop to regulate the output current. The output current is then limited by the current limit protection of the device.
Conclusion
The LT1084CP-5#PBF is a Linear Voltage Regulator from Analog Devices in the PMIC category. It is designed specifically for powering LED lighting arrangements requiring output current of up to 1A. It features a wide voltage operating range of 6V up to 24V and is capable of providing a constant voltage or constant current output. It also has over protection and current limit protection, making it suitable for use in LED lighting applications requiring protection. It is suitable for use in applications such as street lighting, stage lighting, automotive, industrial and commercial lighting, in addition to powering small circuits, meters and remote sensors.
