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.（点击即可咨询芯片详细信息）

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
