Description
Comprehensive resource on power management ICs 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 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 aspects of the physical design like lateral and vertical power delivery, pin-out, floor planning, grounding/supply guidelines, and packaging, are also addressed. A full chapter is dedicated to the design of integrated passives. The text illustrates the application of power management integrated circuits (PMIC) to growth areas like computing, the internet of Things, mobility, and renewable energy.
Includes numerous real-world examples, case studies, and exercises illustrating key design concepts and techniques.
Offering a unique insight into this rapidly evolving technology through the author's experience developing PMICs in both the industrial and academic environment, Design of Power Management Integrated Circuits includes information on:
Capacitive, inductive and hybrid DC-DC converters and their essential circuit blocks, covering error amplifiers, comparators, and ramp generators
Sensing, protection, and diagnostics, covering thermal protection, inductive loads and clamping structures, under-voltage, reference and power-on reset generation
Integrated MOS, MOM and MIM capacitors, integrated inductors
Control loop design and PWM generation ensuring stability and fast transient response; subharmonic 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 sizing
Commonly used level shifters (including sizing rules) and cascaded (tapered) driver sizing and optimization guidelines
Optimizing the physical design considering packaging, floor planning, EMI, pinout, PCB design and thermal design
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.
