uP6213 Datasheet | uPI Semiconductor

Description Features The u P6213A/B is a multi-phase synchronous-rectified Buck controller specifically designed to deliver high quality output voltage for high-performance Intel microprocessors. It integrates a 8-bit DAC that supports Intel VR10 and VR11 tables to set the output voltage between 0.5V and 1.6V. The u P6213A provides programmable 3/4 phase operation. The u P6213B provides programmable 1/2 phase operation. The u P6213A/B also supports dynamic phase selection by PS1/2/3 pins. Operation with phase reduction at light load conditions achieves high efficiency over a wide range of output current. The u P6213A/B includes programmable no-load offset and droop 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. The u P6213A is available in VQFN6x640L package and u P6213B in VQFN4x4-28L package.
