LMZ14203TZE-ADJ/NOPB – TEXAS INSTRUMENTS

The Texas Instruments LMZ14203TZE-ADJ/NOPB is a 3A synchronous step-down converter in a compact, 16-pin, thermally enhanced TSSOP package (NOPB denotes lead-free). It features an adjustable output voltage, allowing for precise voltage regulation from 0.8V to 5.5V, making it highly versatile. The device utilizes a constant frequency, current mode architecture, ensuring fast transient response and excellent line and load regulation. Its internal 3A switch allows for efficient power conversion with minimal external components, reducing board space and simplifying design. The integrated soft-start function minimizes inrush current, protecting the input supply and sensitive downstream circuitry._x000D_
