RT5002 7 + 1 Channel DC/DC PMU with Li-Ion Battery Charger for DSC General Description The RT5002 is a complete power supply solution for digital still cameras and other handheld devices. It includes a 7+1 channel DC/DC power converter unit, a single-cell Liion battery charger, and an I2C control interface. The power converter unit includes one synchronous stepup converter and three synchronous step-down converters for DSP core, I/O, Motor, and memory power supply, one synchronous high voltage step-up converter and one asynchronous inverting converter for CCD± bias, one WLED driver in either synchronous high voltage step-up or current source operation, and one low quiescent LDO for RTC application. All converters are internally frequency compensated and integrate power MOSFETs.
