Newnes has worked with Marty Brown, a leader in the field of power design to select the very best design-specific material from the Newnes portfolio. Marty selected material for its timelessness, its relevance to current power supply design needs, and its real-world approach to design issues. Special attention is given to switching power supplies and their design issues, including component selection, minimization of EMI, toroid selection, and breadboarding of designs. Emphasis is also placed on design strategies for power supplies, including case histories and design examples. This is a book that belongs on the workbench of every power supply designer!

Key Features

*Marty Brown, author and power supply design consultant, has personally selected all content for its relevance and usefulness *Covers best design practices for switching power supplies and power converters *Emphasis is on pragmatic solutions to commonly encountered design problems and tasks

About the editor

Marty Brown

Marty Brown is the author of the Power Supply Cookbook and Practical Switching Power Supply Design. He earned his amateur radio license at the age of 11 and has had electronics as a hobby throughout his life. He graduated cum laude from Drexel University in 1974. His electronic design history includes underwater acoustics with the department of the Navy, airborne weather radar design (digital and SMPS), a satellite CODEC, and process control equipment. He was previously with Motorola Semiconductor as a principle application engineer, where he defined more than eight semiconductor products in the power conversion market and received two patents. He later started his own electronics consulting firm where he designed products from satellite power systems to power-related integrated circuits for many semiconductor companies. He is presently working in the field of digitally-controlled power supplies with Microchip Technologies. He has eight children, five of whom are adopted. His wife is an internationally known writer and speaker in the area of inter-racial adoption and related issues. He presently lives in Scottsdale, Arizona.
