® RT5072 Multi-Channel PMU with Linear Battery Charger for CMOS DSC/DV General Description The RT5072 is a complete power supply solution for digital still cameras and other hand held devices. The RT5072 is composed of a multi-channel DC/DC power converter unit, a single-cell linear Li-ion battery charger, a charger type detector, and an I2C control interface. The power converter unit includes one synchronous stepup converter (CH1), one synchronous step-up/down converter (CH2), three synchronous step-down converters (CH3/4/5), two LDOs with input power as low as 1.5V (CH6/8), one WLED driver in synchronous high-voltage step-up mode or low-voltage current regulator mode (CH7), and a keep-alive LDO (CH9) for RTC application.
