■ DESCRIPTION
The AIC1630A 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
• Default +5V Output Voltage.
