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.
