Description

The MP2303A is a monolithic synchronous buck regulator. The device integrates a 150mΩ high-side MOSFET and a 80mΩ low-side MOSFET that provide 3A continuous load current over a wide operating input voltage of4.7V to 28V. 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 lower than 1μA.This device, available in an 8-pin SOIC and PDIP-8 packages, provides a very compact system solution with minimal reliance on external components.
