LM2724AMX/NOPB

Overview

The LM2724AMX/NOPB is a high-speed synchronous MOSFET driver from Texas Instruments, designed for efficient power switching applications. It features dual N-channel outputs capable of driving both top and bottom MOSFETs in push-pull or half-bridge configurations simultaneously. The device delivers a peak driving current of 3A per channel with a quiescent current of only 195μA. It operates within an input voltage range of 4.3V to 6.8V and includes built-in shoot-through protection and input under-voltage lock-out (UVLO) for enhanced reliability. Packaged in an 8-SOIC surface-mount format, it supports fast response times suitable for modern DC-DC converters.

Feature Summary

• Simultaneous drive capability for top and bottom MOSFETs in push-pull structures
• Integrated shoot-through protection to prevent cross-conduction faults
• Input under-voltage lock-out ensures stable operation during low supply conditions
• High peak output current of 3A per channel for rapid MOSFET switching

Applications

• Synchronous buck converter designs requiring high efficiency
• Half-bridge power supply topologies
• Push-pull DC-DC converter circuits
• General-purpose high-speed MOSFET gate driving in compact power modules

Procurement Notes

Verify the exact part number suffix against the manufacturer's official documentation to ensure compatibility with RoHS standards and specific package variants. Confirm that the ordering information matches the intended reel or cut-tape quantity requirements for your assembly line. Cross-reference the datasheet revision date to ensure all electrical characteristics and pinout definitions are current before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits that require simultaneous control of complementary MOSFETs with minimal dead-time risk. The 3A peak current rating makes it suitable for driving larger gate capacitances without external boost circuitry. Ensure the system input voltage remains within the 4.3V to 6.8V operating range. Consider the 8-SOIC package size for space-constrained PCB layouts where thermal dissipation needs are moderate.

Part Context

This device belongs to Texas Instruments' family of high-speed gate drivers, specifically optimized for synchronous rectification applications. It complements other TI power management ICs by providing robust, isolated-like drive signals for external switching elements. The LM2724 series is engineered to replace discrete logic solutions, offering integrated protection features that simplify design and improve overall system reliability in regulated power supplies.

Replacement Considerations

Check for direct pin-to-pin replacements such as the LM2724A variant if available in your region. Verify that any substitute maintains the same 3A peak current capability and 4.3V-6.8V input voltage range. Ensure the replacement package matches the 8-SOIC footprint and that thermal performance characteristics are equivalent for your specific board layout.
