An Exar Solution for Each Conversion Stage Electronic systems include one or more power conversion stages. From a simple direct connection to a battery to more elaborate inter-connections, each power conversion stage is characterized by a few key parameters. The most important ones are the input voltage range (VIN) from which the conversion has to take place, the output voltage range (VOUT) that the conversion stage has to support and the amount of current or power the conversion stage has to be capable of providing (IOUT). Knowing those three key parameters identifies the type of solution that will be the most adequate to implement. LDO VIN ~ VOUT What is the input voltage VIN?
