7+6 Channels Power Management IC for DSC
General Description
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 CCDbias power supply. CH7
is a WLED driver, auto-selected to be in synchronous high
voltage step-up mode or current regulator mode.
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.
The RT5014 provides over current protection, thermal
shutdown protection, over voltage protection, over load
protection and under voltage protection to achieve complete
protection.
The RT5014 is available in the WQFN-40L 5x5 package.
