The Future of Analog IC Technology MP2403 3A, 32V, 250kHz Integrated Synchronous Step-Down Converter DESCRIPTION The MP2403 is a monolithic synchronous buck regulator. The device integrates a 150mΩ high-side MOSFET and an 80mΩ low-side MOSFET that provides 3A continuous load current over a wide operating input voltage of 4.6V to 32V. 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 to 1μA. This device, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components.
