LM22675MR-ADJ/NOPB – TEXAS INSTRUMENTS

The Texas Instruments LM22675MR-ADJ/NOPB is a monolithic, adjustable output, synchronous step-down converter in a compact 10-pin, 3x3mm QFN package (NOPB). It features a wide input voltage range of 4.5V to 28V, allowing for flexibility in various power supply designs. The device boasts a high switching frequency of up to 2.2MHz, enabling the use of smaller, less expensive external components. Its adjustable output voltage, achieved through external resistor feedback, provides design freedom and precise voltage regulation. The LM22675MR-ADJ/NOPB incorporates internal compensation for ease of design and stable operation. It offers excellent efficiency, typically exceeding 90% at moderate loads, reducing power loss and heat dissipation. Protection features include cycle-by-cycle current limiting, thermal shutdown, and short-circuit protection, ensuring robust operation and system reliability. Common applications include point-of-load converters in industrial control systems, portable devices requiring efficient DC-DC conversion, and battery-powered equipment where high efficiency is crucial. The device’s small size and high efficiency make it particularly advantageous in space-constrained and power-sensitive applications.
