Fundamentals of Power Supply Design

Fundamentals of Power Supply Design draws upon decades of experience from Texas Instruments’ Power-Systems experts. It is written by Bob Mammano, a pioneer in the power supply industry and recognized as “the Father” of the Pulse Width Modulation (PWM) controller. The book starts out with power supply basics such as voltage regulation and power component selection, and then addresses advanced topics such as magnetics design, minimizing EMI, and topology selection. The book is a readable resource that contains equations and theories but also chronicles the history of the power supply industry. Actual measurements are also used throughout to illustrate practical example circuits. This book will be your key reference guide whether you are a new or seasoned power engineer.

Ultra-Low Power Timers Cut Effects of Leakage Currents

A family of ultra-low-power system timers is intended specifically for reducing power during system sleep time. These ICs, called nanotimers, provide various methods for a system to enter a no-power mode, including a simple control signal from a local microcontroller to indicate the start of the off cycle. The system timer then takes care of starting up the circuit after a preprogrammed amount of time. READ MORE…

Linear power for automated industrial systems

When it comes to power management there is a wide variety of topologies that can be employed. However, in automation systems it is common to find a high DC voltage already being used for a motor or in the system’s control lines, most commonly 12V or 24V. While a large number of systems benefit from high-power efficiency DC/DC architectures in order to achieve a lower voltage, there is a great demand for linear regulators (LDOs) to provide voltage regulation to other semiconductor systems in charge of metering, sensing and to control major motor functions. This paper reviews the requirements for linear regulators intended for use within industrial or factory automation systems and their benefits.

Achieving low noise and low EMI performance with DC/DC switching regulators

Mitigating switching regulator EMI and noise is seen by engineers as a black art. Mess with the feng shui of the PCB layout too much, and the system may not pass CISPR standards. Because of this, many power designers simply turn to linear regulators as a guaranteed way to avoid the headache of reducing emissions. But with inferior efficiency, linear regulators then present potential thermal issues that could be avoided by using a switching regulator. How can you get the best of both worlds?

This training series – along with all of the accompanying documentation – is meant to illustrate how engineers can get the superior efficiency of a switcher while also overcoming the challenges of EMI and noise. Both conceptual and practical examples of EMI and noise best practices are presented, along with specific commentary regarding powering automotive systems as well as noise-sensitive analog circuitry.
