DC Switching Voltage Regulators

LM2672M-ADJ/NOPB Description

The LM2672M-ADJ/NOPB from Texas Instruments is a high-efficiency, adjustable-output buck (step-down) switching voltage regulator capable of delivering up to 1A of continuous output current. Part of the SIMPLE SWITCHER® series, it operates over a wide 6.5V to 40V input range, making it suitable for industrial, automotive, and consumer applications requiring robust power conversion. The output voltage is adjustable from 1.21V to 37V, providing flexibility for diverse load requirements. With a fixed 260kHz switching frequency, it balances efficiency and component size, minimizing external filter requirements. The device is housed in an 8-pin SOIC package, optimized for surface-mount assembly, and complies with ROHS3 and REACH environmental standards.

LM2672M-ADJ/NOPB Features

• Adjustable Output Voltage (1.21V–37V): Precision feedback enables custom voltage settings.
• Wide Input Range (6.5V–40V): Supports high-voltage rails common in industrial systems.
• High Efficiency (Up to 92%): Reduces thermal dissipation and improves energy efficiency.
• 260kHz Fixed Switching Frequency: Simplifies EMI filtering and minimizes inductor size.
• Integrated N-Channel MOSFET: Eliminates the need for an external switch, reducing BOM cost.
• Thermal Shutdown & Current Limiting: Protects against overload and overtemperature conditions.
• Non-Synchronous Rectification: Cost-effective for moderate-current applications.
• MSL1 (Unlimited) Rating: Suitable for extended storage and handling.

LM2672M-ADJ/NOPB Applications

• Industrial Power Supplies: Converts 24V/28V industrial bus voltages to lower levels for sensors or microcontrollers.
• Automotive Systems: Powers infotainment, ADAS, or lighting from 12V/24V batteries.
• Consumer Electronics: Efficiently steps down voltage for portable devices, routers, or set-top boxes.
• Telecom/Networking Equipment: Provides regulated power for FPGAs, ASICs, or RF modules.
• Battery-Powered Systems: Extends runtime in IoT devices by minimizing dropout losses.

Conclusion of LM2672M-ADJ/NOPB

The LM2672M-ADJ/NOPB stands out for its wide input range, high efficiency, and compact design, making it ideal for space-constrained or high-reliability applications. Its adjustable output and integrated protections offer versatility across industries, while the SIMPLE SWITCHER® architecture simplifies design-in. Compared to linear regulators or fixed-output switchers, it reduces heat generation and board space, providing a cost-effective solution for 1A step-down conversion. Engineers will appreciate its balance of performance, robustness, and ease of use in demanding environments.
