General Description
The G2205 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
multi-battery designs. On-chip MOSFETs provide up to
92~95% efficiency for critical power supplies. All
channels DC/DC operate at one fixed frequency of
1.5MHz/750KHz to optimize size, cost, and efficiency.
All Synchronous converters operate at pulse skipping
mode at light load. They also feature True-Shutdown
as well as internal compensation to minimize external
component count..
