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..

Built-in HV LDO and RTC LDO

Built-in 4 LDO regulators

Low Power Consumption ( Sleep Mode ) < 10µA.

Built-In Selectable Power ON/OFF Sequence for

4 Channel Synchronous Rectified Converter.

Built-In Power ON/OFF Sequence by I2C for

CCD+,CCD- power, and HVLDO.

Built-In Short Circuit Protection (SCP) & Under

Voltage Protection (UVP)

Cycle-by-Cycle current limit for DC/DC Converter

Built-In Thermal Shutdown Function.
