SM72441MTX/NOPB

Overview

The SM72441MTX/NOPB is a specialized integrated circuit functioning as a Maximum Power Point Tracking (MPPT) controller manufactured by Texas Instruments. It is designed for surface-mount installation within the 28-TSSOP package, which features a width of 0.173 inches (4.40mm). The device is supplied in Tape & Reel packaging to facilitate automated assembly processes. As an MPPT controller, its primary function is to optimize power extraction from energy sources, such as solar panels, by continuously adjusting the electrical operating point.

Feature Summary

• Integrated MPPT controller functionality for maximum power point tracking
• Available in a 28-TSSOP surface-mount package with 4.40mm width
• Supplied in Tape & Reel (TR) format for automated manufacturing

Applications

• Solar energy harvesting systems requiring efficient power optimization
• Photovoltaic (PV) charge controllers
• Renewable energy management units

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as the provided data indicates a Tape & Reel configuration. Confirm that the 28-TSSOP footprint matches the target PCB design constraints. Ensure compatibility with the intended voltage and current levels for the specific MPPT application requirements before procurement.

Selection Notes

Select this component when a dedicated MPPT controller solution is required for photovoltaic applications. The 28-TSSOP package offers a balance between pin count and board space. Consider the Tape & Reel supply format if high-volume automated placement is planned. Verify thermal dissipation capabilities relative to the expected load conditions during system design.

Part Context

This part belongs to the category of Specialized ICs under the broader classification of power management and control solutions. It serves as a key component in systems focused on maximizing energy efficiency from variable DC sources. The NOPB suffix typically denotes a lead-free and halogen-free compliant version of the standard SM72441MTX device.

Replacement Considerations

Direct replacements should be sought among other dedicated MPPT controllers offering similar pin counts and interface requirements. Verify functional equivalence regarding tracking algorithms and input/output specifications. Cross-reference with other Texas Instruments MPPT solutions or competitors' parts that support the 28-TSSOP form factor.
