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.
