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 300A quiescent current.

The output voltage can be internally set to 5V or externally set to an arbitrary value below breakdown voltage of the power switch. Logiccontrolled shutdown mode of AIC1630A is provided for power saving. The low battery detector can be also configured as a linear regulator. 120KHz switching rate reduces the inductor size. Inductors of 25H to 50H inductance are recommended for most applications.
