LM5110-1SDX/NOPB

Overview

The LM5110-1SDX/NOPB is a dual low-side gate driver manufactured by Texas Instruments. It features two independent outputs capable of sourcing and sinking 5A peak current. The device operates with a supply voltage range of 3.5V to 14V. It utilizes a 10-pin WSON package with an exposed pad for thermal management. The driver supports non-inverting logic configuration. Typical propagation delays are characterized at 12ns for fall time and 14ns for rise time. The component is rated for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

Dual independent low-side channel architecture
High peak output current capability of 5A per channel
Integrated negative voltage output capability
Exposed pad thermal design for efficient heat dissipation

Applications

Synchronous buck converter gate driving
Point-of-load (POL) power stage control
DC-DC converter high-frequency switching applications

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the 'DX' suffix corresponds to tape and reel packaging specifications. Ensure the part number matches the exact pinout and thermal pad requirements for the target PCB footprint. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Selection Notes

Select this component when a dual-channel solution is required for synchronous rectification in buck topologies. The 5A drive strength suits medium-power applications requiring fast switching transitions. Consider the 10-pin WSON form factor for space-constrained designs. Evaluate the 3.5V to 14V supply range against the controller logic levels and bootstrap circuit requirements.

Part Context

This device belongs to the LM5110 family of compound gate drivers. It is designed specifically for driving N-channel MOSFETs in low-side configurations. The family emphasizes simplicity and robust performance for industrial and computing power supplies. It serves as a dedicated interface between digital controllers and power switches.
