RT4723

RT4723 Dual Output AMOLED Bias General Description The RT4723 is a highly integrated Boost, LDO 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 steps 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 2.5V to 4.6V, RT4723 is optimized for products powered by single-cell battery and the output current up to 30mA. The RT4723 is available in WL-CSP-15B 1.39x2.07 (BSC) package to achieve optimized solution for PCB space.
