Design of Power Management Integrated Circuits

Comprehensive resource on power management technology affording new levels of functionality and applications with cost reduction in various fields Design of Power Management Integrated Circuits is a comprehensive reference for power management IC design, covering the circuit design of main power management circuits like charge pumps, bridge drivers, linear and switched-mode voltage regulators, along with sub-circuits such as power switches, gate drivers and their supply, level shifters, the error amplifier, current sensing, and control loop design. Circuits for protection and diagnostics as well as system design aspects like pin-out, floor planning, grounding/supply guidelines are also addressed. The text illustrates the application of power management integrated circuits (PMIC) technology to new growth areas like smart buildings, internet of things, and power management for renewable energy, and includes real-world examples, case studies, and exercises (with solutions and Spice netlists for simulation in LTspice via a companion website). Offering a unique insight to this highly protected new technology through the author's experience developing PMIC in the industrial environment, Design of Power Management Integrated Circuits includes information on: Switched mode power supplies (SMPS) essential circuit blocks, covering error amplifiers, comparators, and ramp generatorsSensing, protection, and diagnostics, covering thermal protection, inductive loads and clamping structures, desaturation detection, and under-voltageSubharmonic oscillations in current mode control (analysis and circuit design for slope compensation)DC behavior and DC related circuit design, covering power efficiency, line and load regulation, error amplifier, dropout, and power transistor sizingCommonly used levelshifters (including sizing rules) and cascaded (tapered) driver sizing and optimization guidelines Design of Power Management Integrated Circuits is an essential resource on the subject for circuit designers/IC designers, system engineers, and application engineers, along with advanced undergraduate students and graduate students in related programs of study.
