GMTGeneral Description
The G2257 provide a complete power supply solution for handsets or data card. It contains four dc/dc converters, and one 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 1.5MHz to optimize size, cost, and efficiency. All Synchronous converters are enabled by individual EN pin control and operate at pulse skipping
mode at light load. The G2257 is available in QFN4X4-24 package.
