General Description
The AT1396A/B/C/D provide a complete
power supply solution for digital cameras. They
improve performance, component count, and size
compared to other multi-channel controllers in
2-cell AA, 1-cell Li-Ion, and dual-battery 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.
