RK808  
Power Management System  
1 OVERVIEW  
The RK808 is a complete power supply solution for Portable systems. The highly  
integrated device includes four buck DC-DC converters, eight high performance ldos, two  
low Rds switches, I2C interface, programmable power sequencing and an RTC.  
The RK808 improves performance, reduces component count and size, and therefore  
provides lower cost solution compared to conventional portable designs. The ultra fast  
2MHz current mode DC/DC architecture optimizes the transient performance and is  
compatible with tiny low cost ceramic inductors and capacitors.  
All DC/DC channels  
include integrated MOSFETS. Internal soft-start and compensation circuits minimize  
external components count. Most outputs can be programmed through the I2C interface  
2 FEATURES  
Input voltage range: 2.7V to 5.5V  
2MHz Switching Frequency for bucks  
Current mode architecture for best transient performance  
Internal compensation and soft start  
I2C Programmable output levels and power sequencing  
High efficiency architecture  
Integrated Vout Discharge Circuit for BUCK and LDO  
Power:  
CH1: Synchronous Buck regulator, 5A max  
CH2: Synchronous Buck regulator, 5A max  
CH3: Synchronous Buck regulator, 3A max  
CH4: Synchronous Buck regulator, 2.5A max  
CH6,CH7,CH9,CH11: Linear regulators, 150mA max  
CH8: Low noise and high PSRR linear regulator,100mA max

9.2 DEVICE POWER-ON ENABLE CONDITIONS  
If none of the device power-on disable conditions is met, the following conditions are available  
to turn on and/or maintain the ON state of the device:  
PWRON signal low level.  
Or interrupt flag active (INT low) while the device is off (NRESPWRON = 0)  
The power-on enable condition occurs only if the interrupt status bit is initially low (no  
previous identical interrupt pending in the status register).  
The Interrupt sources expected when the device is off are:  
PWRON low-level interrupt (PWRON_INT = 1 in INT_STS_REG1 register)  
First VDC rising above plug-in threshold (PLUG_IN interrupt(PLUG_IN_INT=1 in  
INT_STS_REG2 register) (Charger plug in interrupt)  
The Interrupt source expected if enabled when the device is off is:  
RTC Alarm interrupt (INT_ALARM_EN=1 in RTC_INT_REG and RTC_ALARM_INT = 1  
in INT_STS_REG register)

PWRON signal low level during more than the long-press delay: TDPWRONLP. The interrupt  
corresponding to this condition is PWRON_LP_INT in the INT_STS_REG register.  
Or Die temperature has reached the thermal shutdown threshold: TSD_STS=1 in  
THERMAL_REG).  
Or Vbat down below UVLO threshold: VB_UV_STS=1 in VB_MON_REG.  
Or DEV_OFF or DEV_OFF_RST control bit set to 1 (value of DEV_OFF is cleared when  
the device is in OFF state).  
9.4 DEVICE SLEEP ENABLE CONDITIONS  
SLEEP signal high level.  
OR DEV_SLP control bit set to 1  
And interrupt flag inactive (INT high): No non-masked interrupt pending  
The SLEEP state can be controlled by programming DEV_SLP and keeping the SLEEP  
state.

2. Dimension b applies to metalized terminal and is measured between 0.15mm and  
0.30mm from the terminal tip. If the terminal has the optional radius on the other end  
of the terminal, the dimension b should not be measure in that radius area.  
3. 0.15mm of dimension b is recommended in PCB layout.
