Switched-mode power supply that transforms the DC input signal into a DC output signal with different amplitude, providing generally an isolation between the input and the output of several hundred volts. There is a wide variety of models and configurations, although the subgroup called POL (Point of load) consists of very high-power converters that do not incorporate isolation.
