The RT5014 is a complete power supply solution for digital still cameras and other hand held devices. The RT5014 is a multi-channel DC/DC power management unit including one synchronous step-up DC/DC converter with load disconnect (CH1), one selectable synchronous step-up/step-down DC/DC converter (CH2), two synchronous step-down DC/DC converters (CH3/4), one synchronous high voltage step-up DC/DC converter (CH5), one asynchronous inverting DC/DC converter (CH6) and one WLED driver in synchronous high voltage step-up mode or current regulator mode (CH7). Besides, the RT5014 also includes six LDO regulators: one RTC_LDO, one High Voltage LDO for CCD+ bias power (CH8), one high PSRR LDO for AFE power (CH9), and three generic LDOs (CH10 to CH12). All P-MOSFETs are integrated and all frequency compensation network needed by DC/DC converters are built-in. RT5014 uses one sequence selection pin SEQ to select five preset sequences and uses I²C control interface to enable channels and adjust CH1/5/6/8/9/10/11/12 output voltage level and WLED dimming ratio and OVP threshold. RT5014 also includes a system reset function to monitor battery voltage. The RT5014 is designed to fulfill the applications for DSC as follows : CH1 is a synchronous step-up output for motor power. CH2 is a selectable synchronous step-up/step-down output for system I/O power. The operation mode is auto-selected by detecting external components topology. CH3 and CH4 are synchronous step-down outputs for DSP core and memory power supply. CH5 and CH8 HVLDO are for CCD+ bias power supply. CH6 is an asynchronous inverting output for negative CCD- bias power supply. CH7 is a WLED driver, auto-selected to be in synchronous high voltage step-up mode or current regulator mode. </p>Besides switching converters, RT5014 has some LDO regulators : CH9 is a LDO for AFE power. CH10 is 3.1V LDO for system, enabled in the preset power sequence. CH11 is a LDO enabled via I²C i/f for memory card and supports Dynamic Voltage Scaling function. CH12 is a LDO for memory card or PLL. CH10 default voltage and enabling are controlled in power sequence selected by pin SEQ. And one keep-alive 3.3V LDO for RTC power supply. </p>The RT5014 provides over current protection, thermal shutdown protection, over voltage protection, over load protection and under voltage protection to achieve complete protection. </p>The RT5014 is available in the WQFN-40L 5x5 package.</p>
