■ DESCRIPTION

The AIC1630 is a DC-DC converter designed to drive an external power switch for more flexibility, especially in higher voltage and larger power applications. Typically six components are required to set up a step up configuration easily achieving efficiency beyond 80. A few more components are required to set up a step down configuration delivering 4A load current with 83 typical efficiency, 86 at 2A load, and 300µA quiescent current.

■ FEATURES
