3A Step-Down DC-DC Converter  
  

The ZL2105 is a complete 3A power conversion IC that combines a synchronous step-down DC-DC converter with integrated synchronous power MOSFETs and key power management functions in a tiny 6 x 6 mm package. Like other members of Zilker Labs' Digital-DCTM product family, the ZL2105 delivers highly efficient performance with integrated power management capabilities and eliminates the need for programming. The ZL2105 is ideally suited for space-restricted applications requiring up to 3A output current and can be used with other Digital-DC devices to provide a complete power system design for systems requiring multiple power domains on a single PCB.

High integration yields 50% reduction in component

count and board space over alternative solutions.
