Switched Inductors: Building Blocks: With insight & intuition

Switched-inductor power supplies are complex mixed-signal systems. They embed analog, analog-digital, and digital functions that set and regulate their outputs. This 49-page handbook shows how to implement and design the building blocks needed for this functionality. Some of the blocks discussed are current and voltage sensors, hysteretic and summing comparators, sawtooth generators and one-shot oscillators, gate drivers and dead-time logic, zero-current detectors, ring suppressors, switched diodes, and shutdown and starter functions. The material also reviews the circuits used to realize some of these blocks, like supply-sensing comparators, push-pull logic, set-reset flip flops, and more. Illustrative figures, equations, and examples complement discussions throughout.
