This article was prompted by a friend of mine asking for help on a board with an ESP32 heart. The board outputs 2.1 V instead of 3.3 V, and it doesn’t seem like incorrectly calculated feedback ...

For some time now, many of EDN’s Design Ideas (DIs) have dealt with ground-referenced, single-power-supplied voltage regulators whose outputs can be configured to produce zero or near-zero volts [1][2 ...

A while back, I published the Design Idea (DI) “Simple PWM interface can program regulators for Vout < Vsense.” It showed some simple circuits for PWM programming of standard bucking-type regulator ...

Analog Devices, Inc. (ADI) introduced the ADP2118 dc-to-dc switching regulator. The highly integrated 3A, step-down, dc-to-dc synchronous regulator includes low on-resistance switching FETs to ...

The messages of conventional wisdom and “rules of thumb” that were perhaps once true can take a long time to change. Consider the widely held view on step-down (buck) switching dc-dc regulators ...

PID controller design has long been central to the stable and efficient operation of automatic voltage regulator (AVR) systems worldwide. Contemporary research in this field focuses on the ...

Electronic air-pressure regulation beats out mechanical methods. Regulated compressed air is widely used in industry for a number of reasons, safety from electrocution being just one of them. A ...
