LM2675N-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675N-ADJ/NOPB is a Texas Instruments SIMPLE SWITCHER power converter featuring a high-efficiency 1A step-down voltage regulator. It operates with an input voltage range of 8V to 40V and provides an adjustable output voltage from 1.21V to 37V. The device utilizes a fixed switching frequency of 260kHz, enabling the use of small external components. It is housed in an 8-pin MDIP package and supports operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic switch for simplified design
• Fixed 260kHz switching frequency reduces component size
• Adjustable output voltage via external resistor divider
• Internal thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for industrial systems
• Battery-powered equipment requiring efficient step-down conversion
• General-purpose 5V or 12V bus distribution networks
• Embedded controller power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free and RoHS compliance. Confirm the N suffix corresponds to the through-hole MDIP package. Ensure the ADJ designation matches the required adjustable output configuration rather than fixed voltage variants. Cross-reference the manufacturer part number with official datasheets to validate pinout and electrical specifications before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 40V must be stepped down to an adjustable level with 1A capacity. The through-hole MDIP package suits prototyping or applications requiring mechanical robustness. Consider the 260kHz frequency for balancing efficiency and passive component size. Verify thermal requirements for the operating environment given the wide temperature range capability.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2675 series of SIMPLE SWITCHER converters. This family includes fixed voltage options (e.g., 3.3V, 5V) and other packages like SOIC and WSON. The LM2675N variant specifically denotes the through-hole construction, distinguishing it from surface-mount counterparts within the same functional family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2675M-ADJ/NOPB offers identical electrical performance in an SOIC-8 surface mount package. LM2675LD-ADJ/NOPB provides the same functionality in a compact WSON-16 package. These alternatives maintain the 1A output and 40V input rating while changing only the physical footprint.
