520 _a"This book is a comprehensive reference for power management IC design. The book covers the circuit design of main power management circuits like charge pumps, bridge drivers, linear and switched-mode voltage regulators. Sub-circuits include 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 will also be addressed."--
