LM5110-2SDX/NOPB

Overview

The LM5110-2SDX/NOPB is a dual-channel low-side gate driver manufactured by Texas Instruments. It provides independent high-current drive for two external N-channel MOSFETs or GaN FETs. The device operates with a supply voltage range of 3.5 V to 14 V and delivers peak output currents of 5 A and 3 A per channel. It features adjustable rise and fall times to control switching speed and minimize EMI. The component is housed in a 10-pin WSON package with an exposed pad for thermal management.

Feature Summary

• Dual independent low-side channels providing asymmetric drive strength
• Adjustable transition times for optimized switching performance
• Negative output voltage capability for enhanced noise immunity
• Integrated bootstrap diode for simplified high-side biasing

Applications

• Synchronous buck converter power stages
• Point-of-load (POL) regulator designs
• DC-DC converter bridge drivers
• Industrial motor control interfaces

Procurement Notes

Verify the specific suffix '2' indicates the 5A/3A current configuration distinct from other variants. Confirm the 'X' suffix denotes tape and reel packaging suitable for automated assembly. Ensure the 'NOPB' designation confirms lead-free and RoHS compliance status as per manufacturer specifications.

Selection Notes

Select this component when asymmetric drive currents are required to optimize turn-on and turn-off speeds differently. Consider the 10-pin WSON package for space-constrained PCB layouts. Evaluate the need for adjustable slew rates to meet electromagnetic interference requirements in sensitive environments.

Part Context

This part belongs to the LM5110 family of compound gate drivers designed for high-efficiency power conversion. It complements controllers like the LM5119 by providing robust output stage driving capabilities. The series supports various packaging options including WSON and MSOP formats for diverse application needs.

Replacement Considerations

LM5110-1SDX/NOPB offers symmetric 5A/5A drive instead of asymmetric 5A/3A. LM5110-3SDX/NOPB shares similar characteristics but may differ in specific pinout or thermal parameters. Verify electrical equivalence before substitution.
