3 Phase Synchronous-Rectified Buck Controller
for Next Generation CPU Core Power
General Description
Features
The uP6212 is a multi-phase synchronous-rectified buck controller specifically designed to deliver high quality output
voltage for high-performance microprocessors and graphic processors.
The uP6212 provides programmable 2/3-phase operation. It also supports dynamic phase selection by PS1/2 pins that automatically switches to single/two phase operation at light load condition. The uP6212 supports both standalone and tracking mode operation. The output
voltage is tightly regulated to local or external reference
voltages.
The uP6212 extract phase current signals by RDS(ON) of low side switches for phase current balance. It senses the output current by DCR of output inductors for load line slope setting and over current protection. This yields both thermal balance and accurate load line adjustment.
The uP6212 includes programmable no-load offset and droop slope functio...
