Electronic system designers, engineers, program managers and original equipment manufacturers (OEMs) must address numerous challenges in the selection or development of an appropriate power supply for their systems. These challenges include a multitude of aspects related to the product development cycle, time-to-market, reliability and warranty, parts availability, and life cycle costs. In some cases, an existing power supply can be readily adapted from a different application. In other cases, it may be necessary to develop a new or custom power supply.
