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 300
μ
A
quiescent current.
The output voltage is internally set to 3V, 3.3V, 5V
or externally set to an arbitrary value below
breakdown voltage of the power switch. Logic-
controlled shutdown mode 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 25
μ
H to 50
μ
H inductance are
recommended for most applications.
