Overview
The MP8126DR-LF-P is a low-noise buck converter IC manufactured by Monolithic Power Systems. It features a single output and operates within an input voltage range of 8V to 14V, providing regulated outputs at 13V, 14V, 18V, or 19V. The device is housed in a 24-VFQFN package with exposed pads, measuring 4x4 mm. It supports surface mount installation and functions reliably across a temperature range of -40°C to +125°C. Designed for LNB applications, it complies with RoHS3 standards and carries an EAR99 classification.
Feature Summary
- Integrated low-noise buck converter topology optimized for sensitive signal processing
- Fixed output voltage options tailored for specific LNB power requirements
- Robust thermal performance supporting extended industrial operating temperatures
Applications
- Low Noise Block downconverter (LNB) power regulation
- Satellite receiver system power management
- RF signal chain voltage conditioning
Procurement Notes
Verify the specific output voltage variant required, as the part number denotes multiple fixed options. Confirm that the 24-QFN package dimensions align with the target PCB footprint. Ensure the design accommodates the exposed pad thermal connection for proper heat dissipation during operation.
Selection Notes
Select this component when designing systems requiring stable, low-noise power for LNB modules. Consider the input voltage window of 8V to 14V against the available supply rails. Evaluate the thermal environment to ensure the junction temperature remains within the specified +125°C limit under maximum load conditions.
Part Context
This device belongs to the MP8126 series from Monolithic Power Systems, specialized for power management in communication infrastructure. It serves as a dedicated solution for converting higher bus voltages to precise levels needed by low-noise amplifiers in satellite reception equipment.
Replacement Considerations
The datasheet indicates the part status is Not Recommended for New Designs. Verify if alternative MPS LNB regulators are currently recommended for new product introductions.
