The RK805 is a complete power supply solution for Portable systems. The highly integrated device includes four buck DC-DC converters, three high performance ldos, I2C interface, programmable power sequencing and an RTC. The RK805 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 The RK805 integrates internal RC oscillator for low cost application which without RTC function
