Global Mixed-mode Technology

G2207

6+6 Channels PMU for DSC

General Description

Features

The G2207 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.

2.5V ~ 5.5V Input Voltage Operation

95% Efficient DC/DC Converter

Built-in 1-ch synchronous boost converter, 1-ch

auto buck-boost converter, 3-ch synchronous

buck converter, 1-ch WLED driver, 4-ch LDOs,

1-ch power switch for CMOS image sensor, and

1-ch low quiescent current LDO for RTC.

32-steps brightness control by I²C for WLED

Driver

Low Power consumption (Sleep Mode ) < 10µA.

Built-In Selectable Power ON/OFF Sequence.

Built-In Short Circuit Protection (SCP), Under

Voltage Protection (UVP), and cycle-by cycle

current limit for DC/DC Converters.

Applications

DSC and DV Power Supply

Built-In Thermal Shutdown Function.

Built-In Battery OVP Function.
