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 ...
