G2202/G2202B

7-Channel DC-DC Converter for DSC

Features

General Description

1.5V ~ 5.5V Input Voltage Operation.

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.

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 Converter, 1 Channel

Non-Synchronous Rectified Current-Mode

PWM Converter.

Selectable Boost Type with LED open

protection or Current Regulation Type LED

Driver.

32-steps brightness control for LED Driver

Built-in HV LDO and RTC LDO

Low Power Consumption ( Sleep Mode ) <

10µA.

Applications
