LM2675M-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675M-5.0 is a DC/DC switching buck converter from the LM2675 series, manufactured by UMW (Guangdong Youtai Semiconductor). It features fixed-frequency 260kHz PWM control and integrates an efficient power switch. The device provides a positive fixed 5V output with a maximum current of 1A. It operates within an input voltage range of 8V to 40V and supports surface-mount installation in an 8-SOIC package (3.90mm width). The component includes internal frequency compensation and offers protection against over-temperature and over-current conditions.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify manufacturer origin as UMW or Guangdong Youtai Semiconductor, distinct from Texas Instruments equivalents. Confirm package type is 8-SOIC and output voltage is fixed at 5.0V. Check for RoHS compliance status. Ensure ordering suffix matches specific tape-and-reel or cut-tape requirements if applicable. Validate pinout compatibility with existing PCB footprints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, cost-effective 1A buck solution is required. It is suitable for applications where a fixed 5V output is necessary from higher input voltages up to 40V. Consider the 260kHz switching frequency for inductor size trade-offs. Verify that the SOIC-8 package fits the mechanical constraints of the design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 series of switching regulators. While functionally similar to Texas Instruments' LM2675, this specific unit is produced by UMW. The series is known for simplicity, requiring minimal external components due to integrated compensation and protection circuits.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct cross-reference may include Texas Instruments LM2675M-5.0/NOPB. Verify pin-to-pin compatibility and electrical specifications before substitution. Alternative manufacturers may offer equivalent functionality but require validation of thermal and electrical performance.
