MXT2482SX

2-2.5A, 23V, 450 kHz Synchronous Rectified Step-Down Converter MXT2482SX/A DESCRIPTION The MXT2482SX is amonolithic synchronous buck regulator. The device integrates 150mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.5 to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on. In shutdown mode, the supply current drops below 1µA. This device, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components.
