PWM-controlled 4-20 mA current-loop transmitter provides galvanic isolation

The accuracy of a 4-20 mA transmitter depends on the integrity of its current-loop path, which must be free of shunt paths and ground loops, both within the transmitter and external to it. External to ...

Voltage Regulators Rev Up PWM-Based Fan Control

The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...

Gold-plated PWM-control of linear and switching regulators

Alright, I admit that the title is a bit over the top. So, what do I mean by it? I mean that: (1) The application of PWM control to a regulator does not significantly degrade the inherent DC accuracy ...

Back to Basics: Voltage Regulators, Part 2

Switch-mode regulators include the buck (step-down) and the boost (step-up), forward and flyback topologies, as well as the SEPIC, hysteretic and multiphase converters. Two basic IC topologies are ...
