Using a microcontroller to manage the operation of a switching power supply allows designers to implement new programmable features previously unavailable from stand-alone controller chips. Many of ...

Switched-mode power supplies are found in electronics all around us. They provide the DC voltages that power our computers, cell phones, chargers, appliances, and myriad other electronic devices.

Many industrial applications in the automotive, automation, appliance, or medical sectors require power supplies that comply with functional safety standards. If the input voltage of such a power ...

Surprising facts, like “old fangled” 3-leg linear regulators (LM317, LM337, LM350, et al.) can be used in shunt regulator topologies can sometimes inspire “new fangled” circuit designs. Figure 1 shows ...

Power supply manufacturers sometimes hear from customers with unfortunate dilemmas, such as, “I need to operate the power supply outside its rated voltage range.” Or, “What happens if I exceed my ...
