LM2726MX/NOPB

Overview

The LM2726MX/NOPB is a high-speed synchronous MOSFET driver manufactured by Texas Instruments. It is designed to drive the external N-channel power MOSFETs in synchronous buck converter applications. The device provides independent high-side and low-side gate drive outputs with optimized rise and fall times to minimize switching losses and cross-conduction. It operates from a supply voltage range suitable for various logic levels and includes features such as under-voltage lockout to ensure reliable operation during power-up and power-down sequences.

Feature Summary

• Provides independent high-side and low-side gate drive outputs for synchronous rectification
• Optimized rise and fall times to reduce switching losses and prevent shoot-through
• Includes under-voltage lockout protection for reliable startup and shutdown

Applications

• Synchronous buck DC-DC converters
• Point-of-load voltage regulation modules
• High-efficiency power supply designs

Procurement Notes

Verify the exact suffix 'MX' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the 'NOPB' designation aligns with RoHS compliance requirements for your specific manufacturing process. Cross-reference the ordering information section of the official TI document to confirm availability and lead time status directly from the source.

Selection Notes

Select this component when designing synchronous rectification stages requiring fast switching speeds. Evaluate the input voltage range and output current capabilities against the target MOSFET gate charge requirements. Consider the thermal performance of the SOIC-8 package in the context of the application's ambient temperature and PCB layout constraints.

Part Context

This part belongs to the LM2725/LM2726 family of high-speed synchronous MOSFET drivers. It serves as a dedicated interface between PWM controllers and power switches, replacing discrete driver solutions to improve efficiency and reduce board space. The device is commonly used in portable electronics and industrial power systems where size and efficiency are critical.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family or equivalent drivers from other manufacturers such as LTC4442 or NCP4413. Verify that alternative parts match the electrical characteristics, particularly propagation delay and peak output current, to ensure circuit stability.
