RT8869A Advanced 2/1-Phase PWM Controller for CPU Core Power General Description The RT8869A is an advanced 2/1-phase synchronous buck controller with 2 integrated MOSFET drivers. It integrates an 8-bit DAC that supports Intel VR11.x CPUs power application. The IC adopts state-of-the-art dynamic phase control capability by PS1 pin and achieves high efficiency over a wide load range. It uses lossless RDS(ON) current sensing to achieve phase current balance. Other features include adjustable operating frequency, adjustable soft-start, short circuit protection, adjustable over current protection, over voltage protection, under voltage protection, power good indication, VR_HOT indication and VR_SHDN indication. The RT8869A is available in a small footprint with WQFN40L 5x5 package.
