Description
  
  The uP6206 is a multi-phase synchronous-rectified Buck controller specifically designed to deliver high quality output voltage for high-performance Intel micro processors. It integrates a 8-bit DAC that supports Intel VR10.X and VR11.X tables to set the output voltage between 0.5V and 1.6V.

The uP6206 provides programmable 3/4 phase operation. It integrates 3 bootstrapped drivers that support 12V + 12V driving capability. 4 phase operation is enabled by a logic level PWM output, achieving optimal balance between cost and flexibility. The uP6206 also supports dynamic phase selection by PS1/2 pins. Operation phase reduction at light load conditions achieves high efficiency over a wide range of output current.

The uP6206 includes programmable no-load offset and slope functions to adjust the output voltage as a function of the load current, optimally positioning it for a system transient.

Other features include accurate and reliable short-circuit protection, adjustable over current protection, and a delayed power OK output. This part is available in VQFN6x6 and VQFN7x7 - 48L package.
