DSC and DV Power Supply
General Description
The G2206 provide a complete power supply solution
for digital cameras. They improve performance,
component count, and size compared to other
multi-channel controllers in 1-cell Li-Ion. 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.
The G2206 also provide Li-ion linear charger with
dynamic power path control. G2206 has USB power
source detection and JEITA compliant. G2206 also
has auto NTC-R 100kΩ/10kΩ detection circuit.
