General Description
The G2202/G2202B 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. Except for CCDBST and LED Driver, All channels DC/DC operate at one fixed frequency of 1.5MHz to optimize size, cost, and efficiency. They also feature True-Shutdown as well as internal compensation to minimize external component count.
