The Future of Analog IC Technology
MP2303
3A, 28V, 340KHz Synchronous Rectified Step-Down Converter
DESCRIPTION
The MP2303 is a monolithic synchronous buck regulator. The device integrates power MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.75V 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 1μA.
This device, available in 8-pin SOIC and 3x3 10-pin QFN packages, provides a very pact system solution with minimal reliance on external ponents.
