The RT4730 is a highly integrated power solution with Buck-Boost, and inverting charge pump to generate positive and negative output voltage. The output voltages can be adjusted with by SWIRE interface protocols. With its input voltage range of 2.9V to 5.2V, the RT4730 is optimized for products powered by single-cell batteries and symmetrical output currents up to 50mA. The RT4730 is available in the WL-CSP-16B 2.34x2.34 (BSC) package.
