GMT致新 G2225RV1U TQFN4x4-28 代理商主推

　　General Description

　　The G2225 provide a complete power supply solution

　　for wearable / sports-cam & IP-CAM application. It

　　contains four dc/dc converters, one power switch and

　　one low quiescent current LDO to power each critical

　　blocks of the system, and is optimized for maximum

　　battery life, featuring a low ground current when in

　　standby mode operation. All channels DC/DC

　　converters operate at selectable frequency of

　　1.5/3.0MHz to optimize size, cost, and efficiency. All

　　Synchronous converters operate at pulse skipping

　　mode at light load.

　　The G2225 is available in TQFN4x4-28 package.

　　Features

　　2.8V ~ 5.5V Input Voltage Operation.

　　95% Efficient DC/DC Converter

　　Built-in 4-ch synchronous buck converter, 1-ch

　　power switch, and 1-ch low quiescent current

　　LDO for RTC.

　　Bucks can be set to lower quiescent current at low load.

　　Low Power consumption (Sleep Mode) < 20μA.

　　1.5/ 3MHz switching frequency.

　　Built-In Power ON/OFF Sequence for PMU.

　　Built-In Short Circuit Protection (SCP), Under

　　Voltage Protection (UVP), and cycle-by cycle

　　current limit for DC/DC Converters.
