RT4723 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.
