XRP7740ILB-NTC-F

Overview

The XRP7740ILB-NTC-F is a specialized Power Management IC (PMIC) from MaxLinear’s PowerXR series, designed for digital power control. It integrates five output regulators: four synchronous buck converters and one Low Dropout (LDO) regulator. The device operates with an input voltage range of 6.5 V to 20 V and features a switching frequency of 1.5 MHz. It supports programmable outputs via I2C interface and includes sequencing capabilities. The component is housed in a 40-TQFN package (6x6 mm) with an exposed pad, suitable for surface mount applications across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates four synchronous buck converters and one LDO regulator within a single PMIC solution.
• Enables digital power management through I2C programmability for precise voltage and current control.
• Includes built-in sequencing logic to manage startup and shutdown sequences of multiple rails.

Applications

• Powering G.hn chipsets such as MOCA 2.0 MXL370x and MOCA 2.5 MXL371x
• Digital power control systems requiring multi-rail regulation
• Communication infrastructure equipment

Procurement Notes

Verify the specific suffix (e.g., NTC, F) against the manufacturer's latest datasheet to ensure correct configuration and compliance status. Confirm availability status as some variants may be discontinued or subject to limited supply. Cross-reference ordering information with official MaxLinear documentation to avoid compatibility issues with existing designs.

Selection Notes

Select this component when a compact, digitally controlled PMIC is required for multi-output applications. Ensure the design utilizes I2C communication lines for programming. Verify that the thermal requirements of the 40-TQFN package are met by the PCB layout, particularly regarding the exposed pad for heat dissipation.

Part Context

This part belongs to the MaxLinear PowerXR family, which focuses on digital power management solutions. These ICs are often tailored for specific communication standards, providing integrated regulation and control features to simplify system design and reduce component count in complex electronic devices.

Replacement Considerations

Check for direct substitutes within the XRP7740 series or compatible MaxLinear PMICs. Verify pinout compatibility and electrical specifications before substitution. Note that some variants may have different suffixes indicating packaging or temperature grades.
