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.

RT4723 Applications

  • AMOLED Bias in Portable Device
