LATEST FEATURE: Novel GaN Design Reduces Volume of AC/DC Converters Substantially - May 2021

Read PDF

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.
