The KF2952A is a monolithic synchronous buck regulator. The device integrates 1 30m2 MOSFETS that provide 2A continwous load current over a wide operating input voltage of4.75V to 18V. 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 SOP package, provides a very compact system solution with minimal reliance on external components.
