General Description
The AT1397A/B provide a complete power
supply solution for digital cameras. They improve
performance, component count, and size compared
to other multi-channel controllers in 1-cell Li-Ion
designs. On-chip MOSFETs provide up to 92~95%
efficiency for critical power supplies, while
additional channels operate with external FETs for
optimum design flexibility. All channels DC/DC
operate at one fixed frequency settable from
100KHz to 1MHz to optimize size, cost, and
efficiency.
