LM2678SDX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2678SDX-5.0/NOPB is a SIMPLE SWITCHER® step-down voltage regulator manufactured by Texas Instruments, featuring a fixed 5 V output and 5 A maximum output current. It operates with an input voltage range of 8 V to 40 V at a switching frequency of 260 kHz. The device utilizes a VSON-14 surface-mount package and supports operation from -40°C to +125°C. Quiescent current is specified at 4.2 mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-side switch eliminates the need for external Schottky diodes
Fixed internal switching frequency simplifies external component selection
Thermal shutdown protection prevents damage during overload conditions

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment power conditioning
Industrial control system power distribution

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SDX' against official manufacturer documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with RoHS directives and check for lead-free status as indicated by the NOPB designation. Confirm that the VSON-14 footprint matches your PCB layout requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required with up to 5 A load capacity. The integrated switch design reduces bill of materials compared to controllers requiring external diodes. Consider the 260 kHz frequency for balancing efficiency and passive component size in space-constrained applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2678 family of SIMPLE SWITCHER regulators, designed for high-efficiency buck conversion. The SDX variant specifically denotes the VSON-14 package type, distinguishing it from TO-263 or TO-220 packages within the same electrical specification family.
