Some circuits need a negative supply voltage that only has to supply a small current. Providing a separate transformer winding for this (possibly even with a rectifier and filter capacitor) would be a ...

High-side current-sense amplifiers (CSAs) are principally used for monitoring the current from a positive supply rail. However, applications like ISDN and telecom power supplies require CSAs that ...

Almost all appliances need a power supply to convert the 100-130 or 220-240 V AC mains voltage to a 3.3 or 5 V DC voltage to supply board electronics. A new regulation to the ECO conception directive ...

It is common for Internet of Things (IoT) devices, industrial sensors, meters, precision, and medical equipment to require both a positive and negative voltage. Often, these voltages must be ...
