The RT4801 is a highly integrated Boost and LDO and inverting charge pump to generate positive and negative output voltage. The output voltages can be adjusted from ±4V to ±6V with 100mV steps by I<sup>2</sup>C interface protocols. With its input voltage range of 2.5V to 5.5V, the RT4801 is optimized for products powered by single-cell batteries and symmetrical output currents up to 150mA. The RT4801 is available in the WL-CSP-15B 1.31x2.07 (BSC) package.
