RT4723 Datasheet (Richtek) - Dual Output AMOLED Bias

RT4723, Dual Output AMOLED Bias

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/0.5
