LM22676MR-5.0/NOPB – TEXAS INSTRUMENTS

The Texas Instruments LM22676MR-5.0/NOPB is a 5A synchronous step-down converter in a compact 6-pin SOT-23-6 package. This specific part number designates a fixed 5.0V output voltage and lead-free, no-halogen packaging (NOPB). It operates from a 4.5V to 28V input voltage range, making it suitable for a wide array of applications. The device incorporates internal high-side and low-side MOSFETs, minimizing external component count and solution size. Its switching frequency is internally fixed, simplifying design and reducing EMI concerns compared to adjustable frequency converters._x000D_

Key features include a 90% typical efficiency at 3A load, enabling power-conscious designs. The LM22676MR-5.0/NOPB utilizes a constant frequency, current-mode control architecture for fast transient response and excellent load regulation. Typical applications include powering low-voltage peripherals from higher voltage sources within portable devices, industrial control systems, and automotive electronics. Its small size and high efficiency make it particularly advantageous in space-constrained applications where minimizing power loss is critical. The fixed 5V output eliminates the need for external voltage adjustment, further streamlining the design process.
