RT4723P
Dual Output AMOLED Bias
General Description
The RT4723P 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 ï0.6V to ï2.4V with 100mV steps
by SWIRE interface protocol. The part maintains the
highest efficiency by utilizing a ï0.33x/ï0.5x mode
fractional charge pump with automatic mode transition.
With its input voltage range of 2.5V to 4.6V, the
RT4723P is optimized for products powered by
single-cell battery and the output current up to 30mA.
The RT4723P is available in WL-CSP-15B 1.39x2.07
(BSC) package to achieve optimized solution for PCB
space.
