Patent ID: 7898233

Claim:
A multiphase voltage regulator system, comprising: a microcontroller unit (MCU) including a digital to analog converter (DAC) for generating a reference voltage; and a timing generator for generating n-phase start timing signals; a comparator for comparing the reference voltage and the output voltage to generate a comparison result; and at least n points of load (POLs) coupled between the MCU and a load for controlling the output voltage in response to the n-phase start timing signals and the comparison result, wherein each POL includes a high-side transistor, a low-side transistor, and a driver for driving the transistors, and wherein the driver includes a D-FlipFlop having a D terminal, a clock terminal, a Q terminal, a /Q terminal and a reset terminal, the D terminal coupled High, the clock terminal coupled to receive a control signal based on a respective one of the n-phase start timing signals, the Q terminal coupled to drive the high-side transistor, the /Q terminal coupled to drive the low-side transistor, and the reset terminal coupled to receive a reset control signal based on the comparison result.
