Voltage conversion and regulation plays a key part in electronics design. In the past, the supply of power rails was more of an afterthought. But today’s designs are more focused on highly efficient power conversion and control, combined with optimization of costs, solution size, and robustness.
Multiple output regulators provide two or more outputs from a single input supply. Outputs can be derived from a combination of buck, LDO, boost, or charge pump topologies depending on the application requirements. Automotive and non-automotive devices are available with a variety of package types, most with exposed pad for excellent thermal dissipation.
