GMTGeneral 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.
