LM2675MX-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675MX-ADJ is a high-efficiency, monolithic integrated circuit step-down switching regulator from the Texas Instruments LM2675 series. It is capable of driving a 1 A load with excellent line and load regulation. The device operates over an input voltage range of 8 V to 40 V and provides an adjustable output voltage ranging from 1.21 V to 37 V. It features a fixed switching frequency of 260 kHz, allowing for the use of small inductors and capacitors. The component is housed in an 8-pin SOIC surface-mount package and supports operation temperatures from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and electrical characteristics. Ensure the ordering code matches the required temperature grade and package variant. Cross-reference manufacturer documentation to validate RoHS compliance status and lead time requirements before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing buck converters requiring a 1 A output current with an input voltage up to 40 V. The 260 kHz frequency is suitable for applications prioritizing compact passive component sizes over ultra-low noise performance. Consider the SOIC-8 package constraints for thermal management in high ambient temperature environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 family of simple-switcher regulators. It shares architectural similarities with the LM2679 (5 A) and LM2672 (0.5 A) variants. The 'MX' designation indicates the SOIC-8 surface-mount package, while 'ADJ' specifies the adjustable output version. This series is designed for straightforward implementation with minimal external components.
