RT8867A - Richtek Technology

RT8867A Advanced 4/3-Phase PWM Controller

The RT8867A is an advanced 4/3-phase synchronous buck controller with 3 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 PS1/2/3 pins and achieves high efficiency over a wide load range. It uses lossless RDS(ON) current sensing to achiev.

Features

include adjustable operating frequency, adjustable softstart, short circuit protection, adjustable over current protection, over voltage protection, under voltage protection, power good indication, VR_HOT indication and VR_SHDN indication. The RT8867A is available in a small footprint with WQFN48L 6x6 package.
