RT4731,PDF数据表下载

RT4731 pdf资料下载The RT4731 is a highly integrated Boost, two LDOs (one channel for AVDD and the other channel for VOP) and inverting charge pump to generate positive and negative output voltage. The negative output voltages can be adjusted from 0.6V to 2.4V with 100mV per step by SWIRE interface protocol. The part maintains the highest efficiency by utilizing a 0.33x/0.5x mode fractional charge pump with automatic mode transition. With its input voltage range of 2.9V to 4.8V, the RT4731 is optimized for products powered by single-cell battery and the output current up to 30mA. The RT4731 is available in UBGA-21B 1.82x3.23 package to achieve optimized solution for PCB space.Datasheet pdf资料数据表下载
