RK808-D Integrated Circuit Chip 2MHz Power Management IC For Portable Systems

Product Description Of RK808-D
RK808-D 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.

RK808-D 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
