uP6213
Multi-Phase Synchronous-Rectified Buck Controller
for Next Generation CPU Core Power
General Description
Features
The uP6213A/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 uP6213A provides programmable 3/4 phase operation.
The uP6213B provides programmable 1/2 phase operation.
The uP6213A/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 uP6213A/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 uP6213A is available in VQFN6x6-
40L package and uP6213B in VQFN4x4-28L package.
