AT1396B 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.
