uP9523R 2-Phase PWM Controller for IMVP9 Voltage Regulator General Description The uP9523R is an Intel® IMVP9 compatible 2-phase PWM voltage regulator controller for mobile/desktop platform application. This device has two embedded 5V MOSFET drivers with integrated bootstrap diodes. The controller supports 2/1-phase configuration to provide flexibility in platform power design. This device combines true differential output voltage sense, inductor DCR current sense, input voltage sense and adaptive voltage positioning to provide accurately regulated power for mobile/desktop CPU. It adopts uPI's proprietary RCOT+TM (Robust Constant On-Time) control topology to have fast transient response and smooth mode transition.
