The RT9986A is a complete power supply solution for digital still cameras and other handheld devices. It includes one synchronous step-up DC/DC converter with load disconnect, one selectable synchronous step-up/step-down DC/DC converter, two synchronous step-down DC/DC converters, one synchronous high voltage step-up DC/DC converter, one inverting DC/DC converter, and one selectable synchronous high voltage step-up/current-source for WLED. In addition, the RT9986A also includes one RTC_LDO, one voltage detector, and one System Reset. All power MOSFETs are integrated in the RT9986A. <p align="justify">The RT9986A is designed to fulfill the applications for DSC as follows : </p><p align="justify">CH1 is a synchronous step-up output for motor or DSC system I/O power </p><p align="justify">CH2 is a selectable synchronous step-up/step-down output for motor or DSC system I/O power </p><p align="justify">CH3 and CH4 are synchronous step-down outputs for DSP core and memory power supply </p><p align="justify">CH5 is a synchronous high voltage step-up output for CCD bias power supply </p><p align="justify">CH6 is an inverting output for negative CCD bias power supply </p><p align="justify">CH7 is a selectable synchronous high voltage step-up/current source for driving WLED </p><p align="justify">The selectable step-up/step-down converter can be auto selected by external component topology. For the RT9986A, all 7-CHs have built in internal compensation. The RT9986A also provides a transformerless inverting converter for supplying CCD power. For the low voltage synchronous step-up and step down converters, efficiency can be up to 95%. </p><p align="justify">The RT9986A provides comprehensive protection features including over current protection, thermal shutdown protection, over voltage protection, overload protection, and under voltage protection.</p>
