LNBP12SP-TR - STMicroelectronics

The LNBP12SP-TR is a sophisticated, monolithic integrated circuit made by STMicroelectronics, designed specifically for driving the supply and control of the LNB (Low Noise Block) downconverter in satellite receiver systems. This device is part of ST's LNB power and control ICs portfolio, and it offers a compact, high-efficiency solution for satellite TV receivers and set-top boxes.

Key Features

• Integrated Step-Up Converter: The LNBP12SP-TR comes with a built-in step-up (boost) DC-DC converter, which is capable of providing a stable output voltage to the LNB, regardless of the fluctuations in the input supply voltage.
• DiSEqC 2.x Compliant: It supports DiSEqC 2.x communication protocol, enabling bi-directional communication between the satellite receiver and the LNB, which is essential for controlling multi-satellite systems.
• Low Power Consumption: Designed with power efficiency in mind, the LNBP12SP-TR minimizes power consumption, making it suitable for energy-sensitive applications.
• Overcurrent and Overtemperature Protection: The device features built-in protection circuits that safeguard the IC from potential damage due to overcurrent conditions or excessive temperature rise.
• Tone Oscillator & Pre-Amplifier: An integrated 22 kHz tone oscillator with a pre-amplifier ensures reliable signaling to switch satellite bands or polarizations.

Applications

The LNBP12SP-TR is primarily used in satellite receiver systems to provide the necessary voltages and signals to the LNB. Its compact size and high integration level make it particularly suitable for set-top boxes, satellite TV receivers, and personal video recorder (PVR) systems.

Package and Availability

STMicroelectronics offers the LNBP12SP-TR in a PowerSSO-24 package, which is designed for surface-mount technology (SMT) and is suitable for automated manufacturing processes. The device's part number ending with "-TR" indicates that it is provided in tape and reel packaging, which facilitates efficient handling and placement during the assembly of electronic equipment.

For designers and engineers looking for a reliable and efficient solution to power LNBs in satellite communication systems, the LNBP12SP-TR from STMicroelectronics presents a compelling option with its robust feature set and proven performance.
