LM2676SD-ADJ/NOPB

LM2676SD-ADJ/NOPB Description

The LM2676SD-ADJ/NOPB from Texas Instruments is a high-efficiency 3A adjustable buck (step-down) switching voltage regulator from the SIMPLE SWITCHER® series. Designed for surface-mount applications, it operates over a wide 8V to 40V input range, delivering an adjustable output from 1.2V to 37V with a 260kHz fixed switching frequency. Packaged in a 14-VSON (5x6mm) tape-and-reel (TR) format, it is RoHS3 compliant and suitable for industrial, automotive, and consumer electronics requiring robust power management.

LM2676SD-ADJ/NOPB Features

• High Efficiency (Up to 95%): Minimizes power loss with integrated N-channel MOSFET and optimized control loop.
• Wide Input/Output Range: Supports 8V–40V input and 1.2V–37V adjustable output, ideal for diverse voltage conversion needs.
• 3A Continuous Output Current: Delivers stable power for high-load applications without external FETs.
• Fixed 260kHz Switching Frequency: Reduces output ripple and simplifies EMI filtering.
• Built-in Protection: Includes thermal shutdown, current limiting, and under-voltage lockout (UVLO).
• Compact & Reliable: MSL1 (Unlimited) moisture sensitivity ensures long shelf life, while REACH unaffected status meets environmental standards.

LM2676SD-ADJ/NOPB Applications

• Industrial Power Systems: Used in PLCs, motor controllers, and factory automation due to its wide input tolerance and robustness.
• Automotive Electronics: Powers infotainment, ADAS, and lighting systems where 40V input capability handles load-dump conditions.
• Consumer Electronics: Ideal for set-top boxes, routers, and LED drivers requiring high efficiency in compact designs.
• Battery-Powered Devices: Extends runtime in portable equipment by minimizing quiescent current.

Conclusion of LM2676SD-ADJ/NOPB

The LM2676SD-ADJ/NOPB stands out for its high efficiency, wide voltage range, and integrated protections, making it a superior choice over discrete solutions or lower-current regulators. Its small footprint, reliability, and compliance with RoHS3/REACH suit demanding applications in automotive, industrial, and consumer markets. Engineers benefit from simplified design with TI’s SIMPLE SWITCHER® architecture, reducing BOM cost and development time while ensuring performance.
