Non-Isolated Step-Down DC-DC Converter Slide 6

The top section of this slide is a comparison of the MPM80 series versus an implementation with typical step-down converter IC. The MPM80 series only requires 3 - 5 external components compared to up to 12 external components with conventional step-down converter IC’s. Concerns regarding design aspects such as part placement, PCB trace patterns and the selection of proper inductors are minimized. The lower section of this slide is a comparison when using a power supply with a series linear regulator IC. Since the maximum input voltage of the MPM80 series is 30 V, an additional tap off of the flyback transformer and a heat sink for cooling which is required in the case of a series linear regulator IC, is unnecessary. In addition, since a ceramic capacitor can be used instead of an electrolytic capacitor for the output filter, it allows the user to have a more efficient, less heat dissipating power supply that does not take much PCB area, comparing to the approach using a series linear regulator IC.
