Integrated Point-of-load (IPOL) voltage regulator for high-density applications

The IR3883MTRPBF is an easy-to-use, fully integrated and highly efficient DC-DC regulator for every high density Point of Load applications. It is perfectly suited for NetCom, Telecom, Servers and Storage applications where high efficiency, high reliability and good thermals are required. It provides up to 3 A continuous current from 4.5 V to 14 V in a small 3 mm x 3 mm PQFN package. This voltage regulator employs an enhanced stability Constant On-time engine that makes it stable with ceramic capacitors without compensation for an easy design and layout. Solutions from competitors require extra components for stability and for ripple injection. The IR3883MTRPBF can save five components in a design.
