General Description

The G2249RG1U provide a complete power supply solution for handsets or data card. It contains 7 dc/dc converters and 3 LDOs to power each critical blocks of mobile phone, and is optimized for maximum battery life, featuring a low ground current when in standby mode operation. All channels DC/DC converters operate at one fixed frequency of 3.0MHz or 1.5MHz to optimize size, cost, and efficiency. All Synchronous converters operate at pulse skipping mode at light load.
The G2249 features a I2C compatible interface.
The G2249 is available in TQFN5X5-40 package.
