Sinopsis

This book describes power management ICs to tackle the challenges for both accurate and efficient power delivery for today's high performance processors. A double-edge multi-phase low-latency pulse width modulator IC is implemented in 0.18 um CMOS process with 0.04 mm2 active area and demonstrates a fast double-edge pulse width modulation scheme which is important for achieving fast controller response for high bandwidth applications. A multi-mode 4-phase digital IC controller for voltage regulator application is implemented in 0.18 um CMOS process with 4 mm2 active area. The controller combines load current feedforward with voltage mode feedback to achieve fast transient response and multi-mode control strategy improves the converter efficiency by at least a factor of ten in light load condition. A load-scheduled integrator array is developed in the controller IC which improves the load transient response when voltage regulator transitions between continuous conduction mode and discontinuous conduction mode.
