The LNBP11LPUR is a cutting-edge component designed and manufactured by STMicroelectronics, a global leader in semiconductor solutions. This product is a monolithic linear and switching voltage regulator specifically intended for satellite set-top box (STB) applications. It is designed to provide the necessary voltages to the Low Noise Block downconverter (LNB) in satellite receivers, facilitating the reception of satellite signals.

Key Features

• Versatile Power Management: The LNBP11LPUR is capable of supplying a fixed output voltage of 13V or 18V, which is selectable via the VSEL pin. This flexibility allows it to cater to different LNB requirements.
• Built-in Tone Oscillator & DiSEqC Encoder: It includes an integrated 22kHz tone oscillator that is DiSEqC 1.X compliant, enabling the control of satellite dish positioners and selection of different satellite signals.
• High Efficiency: The device features a low-dropout post regulator and a step-up DC-DC converter with an internal power switch, ensuring high power efficiency and reduced heat generation.
• Protection Features: The LNBP11LPUR is equipped with several protection mechanisms, including overcurrent and thermal shutdown protection, to safeguard the circuitry from potential damage caused by abnormal operating conditions.
• Minimal External Components: Its design requires a minimal number of external components, which simplifies the design of the power supply section in satellite STB systems.

Applications

The LNBP11LPUR is primarily utilized in satellite receiver systems where it powers the LNB. Its robust feature set makes it ideal for use in both residential and commercial satellite STB units.
