Product Descriptions
The MP2309 is a monolithic synchronous buck regulator. The device integrates 140mΩ MOSFETS that provide 1A continuous load current over a wide operating input voltage of 4.75V 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. Shutdown mode drops the supply current to 1µA.
This device, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components.
