LM5071MT-50/NOPB

Overview

The LM5071MT-50/NOPB is a synchronous buck switching controller manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 60 V and supports output voltages down to 0.9 V. The device integrates a high-side and low-side gate driver capable of sourcing 2 A and sinking 3 A, respectively. It features adjustable switching frequencies from 100 kHz to 1 MHz and includes programmable soft-start, current limit, and overvoltage protection. Packaged in a thermally enhanced HTSSOP-16 (MT) case, it is designed for industrial and automotive applications requiring robust power management.

Feature Summary

• Integrated high-current gate drivers for efficient synchronous rectification
• Built-in protection mechanisms including overvoltage, undervoltage, and thermal shutdown
• Flexible configuration via external resistor programming for frequency and timing parameters

Applications

• Industrial point-of-load regulation
• Automotive infotainment and body control modules
• Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix 'MT' corresponds to the HTSSOP-16 package variant when ordering. Confirm that the '-50' designation aligns with the required input voltage specifications for your system design. Ensure compatibility with the intended switching frequency range during component selection.

Selection Notes

Select this controller for designs requiring a wide input voltage range up to 60 V. Consider the integrated gate drive strength for driving external MOSFETs efficiently. Evaluate the need for external compensation components based on the desired loop stability and transient response requirements.

Part Context

This component belongs to the LM5071 family of synchronous buck controllers.
