uP1649Q Datasheet 1/2/3/4-phase Pwm Controller

Manufacturer: uPI Semiconductor

Overview: uP1649Q 1/2/3/4-Phase PWM Controller with SMBus Digital Interface Control for VR12.

Datasheet Details

The uP1649Q is a VR12.5 compliant CPU power controller supports up to 4 phases. The integrated I2C interface programmability makes the uP1649Q high performance and easy design. Designer can define different power scenario for different current states to optimize the performance and efficiency. The uP1649Q combines true differential voltage sensing, differential inductor DCR current sensing, input voltage feed-forward and adaptive voltage positioning to provide accurately regulated power for des.
