Some applications require a positive voltage to be generated from a negative input voltage. This can be done either by using a transformer based topology, such as a flyback converter, or with a ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

High-efficiency step-down switching regulators for positive voltages are very common, however negative step-down switching regulators (negative voltage in, negative voltage out, common ground) are not ...

Electronic circuit designs often require power sources with negative output voltages. There are many different ways of producing a negative output voltage from a positive input voltage. One option is ...

Fig 1. An SPI-based output driver (in this case, an L9822 octal relay driver from STMicroelectronics) can be used to provide a random mix of I/O pins at the chip’s output. The circuit in (a) senses a ...
