LM2675M-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675M-3.3/NOPB is a Texas Instruments step-down switching regulator operating at a fixed 3.3V output with a maximum load current of 1A. It accepts an input voltage range from 8V to 40V and utilizes a 260kHz internal oscillator for efficient power conversion. The device features a SOIC-8 surface-mount package, supports junction temperatures up to 125°C, and includes built-in thermal shutdown and current limiting protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-current switch capable of delivering up to 1A output
Fixed 3.3V output option eliminates external feedback resistor networks
Internal 260kHz switching frequency enables compact passive component selection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Input voltage step-down for microprocessor supply rails
Battery-powered equipment requiring efficient DC-DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB confirms lead-free and RoHS compliance status. Confirm the -3.3 designation matches the required fixed output voltage. Ensure the M package variant aligns with the intended surface-mount PCB footprint requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 3.3V rail is needed within an 8V to 40V input window. The SOIC-8 package suits space-constrained designs. Consider the LM2675M-ADJ if adjustable output flexibility is preferred over the fixed configuration.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2675 series of simple-switcher regulators. It shares core topology with other variants in the family but differs in output configuration and package type compared to through-hole or adjustable versions.
