RT4733 Datasheet | Richtek

Power Solution for Wearable AMOLED Products 1 General Description The RT4733 is a highly integrated power solution with a buck-boost converter and an inverting charge pump to generate negative output voltage. The output voltages can be adjusted via the SWIRE interface protocol. The part maintains high efficiency by utilizing a - 0.5x/- 1x mode fractional charge pump. With an input voltage range of 2.9V to 5.5V, the RT4733 is optimized for products powered by single-cell batteries and can supply symmetrical output currents up to 150mA. The RT4733 is available in the WL-CSP-21B 1.31x2.91 (BSC) package. The remended junction temperature range is - 40C to 125C, and the ambient...
