MP8126DF-LF

Overview

The MP8126DF-LF is a specialized power management integrated circuit designed for Low-Noise Block downconverter (LNB) applications. It functions as a converter and LNB regulator IC with a single output, housed in a 24-QFN (4x4) package. The device supports input voltages ranging from 8V to 14V and provides regulated output levels of 13V, 14V, 18V, or 19V. It operates within a temperature range of -40°C to 125°C and is classified as not recommended for new designs.

Feature Summary

• Integrated LNB power supply and control voltage regulation
• Wide input voltage tolerance for satellite receiver systems
• Compact surface-mount packaging for space-constrained layouts

Applications

• Satellite television receivers
• LNB power supply circuits
• Control voltage regulation for satellite components

Procurement Notes

Verify component status carefully, as the MP8126 series is marked as not recommended for new designs. Confirm availability through authorized distributors, noting that standard packaging quantities may apply. Ensure compatibility with existing system requirements before procurement due to potential obsolescence constraints.

Selection Notes

Select this component for legacy satellite receiver designs requiring specific LNB control voltages. Evaluate the 8V to 14V input range against available power sources. Consider the 24-QFN package dimensions for PCB layout constraints. Verify that the available output voltage options meet the target LNB specifications.

Part Context

This part belongs to the MP8126 family of LNB regulators manufactured by Monolithic Power Systems. It serves as a dedicated solution for powering and controlling satellite low-noise block downconverters. The DF suffix indicates a specific tape and reel packaging configuration distinct from other variants in the series.
