G2204/G2204B
G2204C/G2204D
Global Mixed-mode Technology Inc.
7-Channel DC-DC Converter for DSC
Features
General Description
1.5V ~ 5.5V Input Voltage Operation.
The G2204 provide a complete power supply solution
95% Efficient DC/DC Converter.
Highly Integrated 7-CH DC/DC with integrated
Power MOSFETs.
Main Channel Selectable Buck or Boost for
2*AA or Li-Ion Application.
Built-in 6 Channel Synchronous Rectified
Current-Mode PWM/PSM Converter, 1 Channel
Non-Synchronous Rectified Current-Mode
PWM Converter.
Selectable Boost Type with LED open
protection or Current Regulation Type LED
Driver.
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.
32-steps brightness control for LED Driver
Built-in HV LDO and RTC LDO
Low Power Consumption ( Sleep Mode ) <
10uA.
