| Novel GaN Design Reduces Volume of AC/DC Converters Substantially - May 2021 |
April, 22 2021 |
| Power Integrations recently released a GaN-based IC called MinE-CAP, intended for use in a new generation of mobile credit card-sized chargers or offline power supplies. By halving the size of the high-voltage bulk electrolytic capacitors required in offline power supplies, this IC enables a reduction in adapter size of up to 40%. The device also reduces in-rush current making NTC thermistors unnecessary, increasing system efficiency and reducing heat dissipation. |

| Design tools have been developed over the past ten years to help power supply designers create single DC to DC power supplies. These tools feature parts selection, material cost calculation simulation and prototype procurement. This has simplified the design process and reduced time-to-market. But with design complexity increasing, the need for ten or more power supplies on a PC board has increased the challenge. |

| Active ORing Solutions in Redundant Power System Architectures |

| In its simplest form, an ORing device is a diode that protects the system against an input power source fault
condition. A diode ORing device allows current to flow in one direction only, thus isolating the fault from the redundant bus, allowing the system to keep running off the remaining redundant power source(s). |
