AP2953AS8PR Datasheet PDF - Wuxi Chipown Micro-electronics limited

Description
   The AP2953A is a monolithic synchronous buck regulator. The device integrates 100mΩ MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.75V 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.
