RT5047BGSP

Overview

The RT5047BGSP is a single-output LNB supply and control voltage regulator manufactured by Richtek. It utilizes a boost topology to generate an adjustable output voltage ranging from 13.3 V to 19.3 V, supporting a maximum output current of 500 mA. The device operates with a minimum input voltage of 8 V and features a switching frequency of 700 kHz. It has a static current of 16 mA and functions within a temperature range of -40°C to +85°C. The component is housed in an SOP-EP-8 package.

Feature Summary

• Designed specifically for Low Noise Block downconverter (LNB) power supply and control applications.
• Integrates a boost converter topology for efficient voltage step-up regulation.
• Provides a single adjustable output channel suitable for satellite receiver systems.

Applications

• Low Noise Block downconverter (LNB) power modules
• Satellite television receiver systems
• Control voltage generation for RF front-end components

Procurement Notes

Verify the specific suffix BGSP against the manufacturer's datasheet to confirm pinout and thermal pad configuration. Ensure compatibility with SOP-EP-8 surface mount assembly processes. Check humidity sensitivity levels and reflow soldering profiles prior to manufacturing integration. Confirm RoHS compliance status through official documentation.

Selection Notes

Select this component when a dedicated boost regulator is required for LNB bias tee circuits. The fixed 700 kHz switching frequency aids in EMI filter design. The wide input voltage range accommodates various vehicle or home power sources. Consider the 500 mA current limit for typical LNB power requirements.

Part Context

This part belongs to Richtek's portfolio of switching voltage regulators under the PMIC category. It is distinct from buck converters like the RT6201 series due to its boost topology. The RT5047 series is specialized for communication infrastructure rather than general-purpose computing power delivery.

Replacement Considerations

RT5047BS-A is listed as an alias for this part number. Verify electrical equivalence before substitution.
